[Q] Official ICS - support for USB OTG? - HTC Desire S
Hi there,
I know that some of you were able to connect peripheral devices to their phones.
Has anyone of you tested this with the ICS stock kernel? When looking at /proc/config.gz it seems to me that all things neccessary for USB OTG are contained in the kernel.
Did you always use a special "OTG cable" or were you able to force the controller into host mode?
I'm playing with several USB hubs at the moment but I'm stuck.
Have a nice day,
Markus
You need Y-cable for getting the VBUS to both phone and hub.
Well, I removed a diode from my hub and put a label on it saying "do not connect to computer" .
Now, as soon as I connect my phone to the hub's upstream port, it starts charging. But still dmesg doesn't say anything about a switch to host mode .
Check ID pin value on the cable you're using. You're most likely using the standard A-to-microB cable, meant for device. You need A-to-microA, or just hack your cable and tie ID pin low in the microB plug, turning it into microA.
Now I made sure I'm using the right cable, but still it doesn't work.
This has to do with the stock kernel. If you look at "arch/arm/mach-msm/board-saga.c", line 3168, it says "USB_PERIPHERAL". If you change this to "USB_OTG" and compile it using the default config file, the kernel still won't recognize a OTG cable. But you can mount debugfs: "mount -t debugfs none /sys/kernel/debug" and look at "/sys/kernel/debug/msm_otg/mode". This file contains "none", if no cable is plugged in, or "peripheral" else. If you try to overwrite it with "echo host > mode", something happens according to dmesg:

It seems like something is immediately switching back to "peripheral", probably it's got to do with the "carkit driver":

The file "drivers/usb/otg/msm_otg.c" has been adjusted by HTC and I'm afraid you'd have to revert these changes to make host mode work. Unfortunately, I don't think I have enough knowledge about this to do it myself. But probably this is interesting to some of you who are working on custom ICS kernels .
Hello,
Did you manage to make it work with ICS?
Thank you.
Well, no. And currently I've got neither the time nor the knowledge to I'm afraid. But it was possible in Android 2.3.5 by using a kernel hack. As far as I know amidabuddha is playing around with this, too, but wasn't successful yet as we were not able to get the source code of the modified kernel.
Finally, I did it! :victory: ... At least partially.

At the moment, you have to switch between peripheral mode and host mode manually, as I explained in my post above. When switching to host mode, the phone stops charging, so this isn't really OTG now.
Patching is much easier than we thought, as all necessary code already exists in the stock source code. HTC just seems to have "forgotten" one line...
I'll append a patch for HTC's ICS stock source code and the .config file I used.
Using the patch and the kernel config I appended OTG mode finally works as it should. The phone switches between peripheral mode and host mode automatically depending on the cable's ID pin and starts charging even when in host mode. It is possible now to connect usb hid devices as well as usb sticks, card readers and so on, I even tried remote triggering a Canon DSLR using "Remote Release".
The appended kernel config file is based on saga_defconfig, the only changes I made are those necessary for OTG. It should still be possible to connect the phone to a car kit or a desktop dock, although I can't test that.
Wow. I worked on this thing for three days and got it working a couple hours ago. And now I find out that you made the the same thing. I patched exactly the same lines. What a coincidence
So your phone starts charging in host mode, too? A few seconds after you plugged in the otg cable?
There's still something wrong I'm afraid:
Code:
<6>[ 1061.087646] [USBH] !id
<6>[ 1061.087738] [USBH] Avail curr from USB = 0
<6>[ 1061.284545] [BATT][tps65200] Set VDPM back to original V: regh 0x03=83

<6>[ 1063.091400] [BATT][tps65200] Switch charger OFF
Although the LED lights up the charger is switched off. You can see that either in the kernel log or in Settings -> Power. There it says "discharging" for me.
There is not even ACA support for the "CI_45NM_INTEGRATED_PHY" as I expected in the first place, so I think we must find a way to force it into ac charging mode when the id pin is grounded. "drivers/usb/otg/msm_otg.c" should be the right place to start...
Hi guys.
I have pulled the request by astro757 and combined it with some more entries from the defconfig by engelmarkus that *could* eventually make the storage host operational. See here. There are some differences in your patches.
Has anyone of you tried that? I do not have a cable to test it and before release I would like to be sure that it is working. Credits will be given to you both of course.
Btw engelmarkus, I see you defconfig is from CM. Am I right?

Well, I downloaded your repository and compiled it. HID devices do not work:
...
<3>[ 479.265350] generic-usb 0003:046E:52CF.0002: can't reset device, msm_hsusb_host.0-1.3/input1, status -71

...

This sounds almost like https://bugzilla.novell.com/show_bug.cgi?id=734754 .
EDIT:
HID devices do work, but you have to plug them in before you power the hub. HID devices plugged in afterwards are not recognized at all. I think there was some change in the patches between 3.0.16 and 3.0.59 that is responsible for this weird behaviour.

I got my saga_defconfig from "saga-ics-crc-3.0.16-62a67df" and made a few changes. I never looked into the CM sources.
Hey, I was wondering what you changed in msm_otg.c. I'm trying to do similar with a Nexus 4 right now, and have modified msm_otg.c for crude support with /sys/kernel/debug/msm_otg/mode (thanks CaptainMuon), but on unplug of the otg cable, mode gets locked to "none" until the device is rebooted. There's also no auto-switching between host and peripheral when an otg cable/device is inserted (externally powered y-cable).
Thanks for any help

We didn't change this file at all.

Problem with charging my phone
My phone doesnt charge when connected to a wall charger, but will charge when connected to anything else through USB. I have tried several different wall adapters and USB cables. Im currently charging my phone via my computer or Xbox 360. Can someone please help me solve this problem.
Did you try another wall charger? Sent from my SGH-T959V using xda app-developers app
Yes I tried several
Which ROM and kernel? Will your wall charger successfully charge other devices? Posted from my SGS4G, thanks to Team Acid development
Yes it does charge other devices
It would help to have some kernel messages when you are plugging and unplugging a "good" charger, as well as the one that fails. When you ahve a chance, would you: Plug your phone into a known good charger Wait half a minute Unplug your phone from the charger Run in a terminal window (*not* adb over USB) # dmesg > /sdcard/good-charger.dmesg Plug your phone into the bad wall charger Wait half a minute Unplug your phone from the charger Run in a terminal window # dmesg > /sdcard/bad-charger.dmesg There shouldn't be any personal information in those files, but I'd check them first to make sure. Once you have those two files, if you would upload them to pastebin or the like, then post the URLs here. If you don't already have a terminal emulator, I like https://play.google.com/store/apps/details?id=jackpal.androidterm

The phone is trying to draw up to 1000 mA from an AC charger. 869 mA is close, but I am thinking that the wall charger may not be able to supply enough current for the smart phone. On the charger's side, probably in nearly illegible writing, you should see something like "Output: 5V, 500 mA" or "Output: 5V, 1000 mA" or "Output: 5V, 1.0 A" -- the first is probably going to cause problems, the last two should be "strong enough."

Hello, I have an issue I can't resolve by myself. I would like to use Prolific pl2303 usb<->serial adapter. I can't make it work. I see /dev/ttyUSB0 but it doesn't work as serial port. In dmesg I see: <6>[ 1844.751839] usb 2-1.4.5: new full speed USB device number 10 using usb20_host <6>[ 1844.853186] usb 2-1.4.5: New USB device found, idVendor=067b, idProduct=2303 <6>[ 1844.853292] usb 2-1.4.5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 <6>[ 1844.853395] usb 2-1.4.5: Product: USB-Serial Controller C <6>[ 1844.853462] usb 2-1.4.5: Manufacturer: Prolific Technology Inc. <6>[ 1844.855524] option 2-1.4.5:1.0: GSM modem (1-port) converter detected <6>[ 1844.856420] usb 2-1.4.5: GSM modem (1-port) converter now attached to ttyUSB0 Obviously it should be handled by pl2303.ko, but it seems it's not so. How to make pl2303.ko handle the device? Thanx in advance.
OTG cable + Card reader = not working.
Hey Im running US retail on my XT 1032, with root and unlocked bootloader. I have the last OTA update with OTG fix. Since I updated I've been trying to connect my Card reader to my moto g with the OTG cable, but it doesn't work, it doesn't recognize it. I tried with two differents readers and two micro sd, both in NTFS, FAT and FAT32. I tried a pen drive and it works fine. Its weird because meenova its a card reader too and it works perfectly (I havent got one, and its really hard to buy it in my country because of the costumes policy). I have a Sandisk 16gb Ultra, so, I really want to fix this.
Any idea?

Have a look at the following post for more info. http://rootzwiki.com/topic/33033-otg-usb-insufficient-available-bus-toolthingy/ A "dmesg" output will help you to identify why the device is not been detected.

[Q] External Wi-Fi USB adapter
Hello, guys! I got Nexus 5 running vanilla AOSP Android 4.4.3 compiled by myself. It works like a charm. I would like to use external Wi-Fi USB adapter with my Nexus 5. I've tried to use AWUS036NHA (with Atheros AR92721 chip) and two other models from different vendors. Every time I get the same error. So, what have I done? I've rebuilt kernel to add support for my devices (in usual Linux way) and added firmwares they need to /vendor/firmware. When I plug AWUS036NHA into my phone I get the following (dmesg): Code: <6>[ 1587.856305] usb 1-1: new high-speed USB device number 2 using xhci-hcd <6>[ 1587.887070] usb 1-1: New USB device found, idVendor=0cf3, idProduct=9271 <6>[ 1587.887129] usb 1-1: New USB device strings: Mfr=16, Product=32, SerialNumber=48 <6>[ 1587.887221] usb 1-1: Product: UB91C <6>[ 1587.887273] usb 1-1: Manufacturer: ATHEROS <6>[ 1587.887365] usb 1-1: SerialNumber: 12345 <4>[ 1587.887857] usb 1-1: ep 0x1 - rounding interval to 32768 microframes, ep desc says 0 microframes <4>[ 1587.888693] usb 1-1: ep 0x82 - rounding interval to 32768 microframes, ep desc says 0 microframes <4>[ 1587.888968] usb 1-1: ep 0x5 - rounding interval to 32768 microframes, ep desc says 0 microframes <4>[ 1587.889115] usb 1-1: ep 0x6 - rounding interval to 32768 microframes, ep desc says 0 microframes <6>[ 1587.890044] usb 1-1: ath9k_htc: Firmware htc_9271.fw requested <6>[ 1588.180755] usb 1-1: ath9k_htc: Transferred FW: htc_9271.fw, size: 51272 <6>[ 1588.416902] ath9k_htc 1-1:1.0: ath9k_htc: HTC initialized with 33 credits <6>[ 1588.644279] ath9k_htc 1-1:1.0: ath9k_htc: FW Version: 1.3 <7>[ 1588.644345] ath: EEPROM regdomain: 0x833a <7>[ 1588.644351] ath: EEPROM indicates we should expect a country code <7>[ 1588.644360] ath: doing EEPROM country->regdmn map search <7>[ 1588.644367] ath: country maps to regdmn code: 0x37 <7>[ 1588.644374] ath: Country alpha2 being used: GB <7>[ 1588.644379] ath: Regpair used: 0x37 <6>[ 1588.648677] ieee80211 phy3: Atheros AR9271 Rev:1 <7>[ 1588.650804] Registered led device: ath9k_htc-phy3 It seems to me that everything here is ok. But when I try to switch on the adapter (ifconfig wlan1 up) I get an error (dmesg): Code: ADDRCONF(NETDEV_UP): wlan1: link is not ready By the way, "ifconfig" command shows no error, but certainly it doesn't swith my device on. So, I got the same error with 3 different adapters. I got no idea about possible ways of solving this problem. Please, share your ideas, I'm really stuck Looking forward for your help. And thanks in advance!
