[Q] [GT-P3100] Problem with mounting USB flash with OTG cable - Galaxy Tab 2 Q&A, Help & Troubleshooting

hi
i have a GT-P3100 with CM11 (cyanogenmod) (kitkat 4.4.2) on it.
when i plug a OTG cable with USBdisk to my tablet it works properly at first.
but if i suddenly unplug USB flash without un-mounting it from setting->storage it will not be mounted again and i have to reboot tablet to OTG working again.
is there a way to manually preparing SD card ( usbdisk) ?

about 2 weeks ao i installed the revolution Rom on my asus eee pad transformer.
But now the USB ports of my dckingstation are not beiing regonized any more when i put a usb stick or something in it.
Any one that has an solution for it?
Restart your tablet.
For me restarting after inserting sticks or cards brings them up. You need to reboot each time. Will show both usb and SD if all inserted and then you reboot.
