I am having a problem with my USB thumb drive. If the drive is connected |
| 4 |
to the system on boot, the device file /dev/sdb is created, and I'm able |
| 5 |
to mount and use my thumb drive normally. If I remove the thumb drive |
| 6 |
and then replace it, or attach the thumb drive after the system has |
| 7 |
booted, the device file is not created. Does anyone have any ideas as to |
| 8 |
what may be causing this? I have tried a kernel with the USB drivers |
| 9 |
compiled into the kernel and compiled as modules, and I get the same |
| 10 |
thing. The output of dmesg is as follows: |
