USB flash disk not recognised

Post by samden »

I am running Mint 8 (main edition) on an IBM ThinkCentre 8142. I am having difficulty using USB flash drives.

When I plug in the device, it does not appear in Nautilus. When I run lsusb, I get the following output:

Code: Select all

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 046d:c517 Logitech, Inc. LX710 Cordless Desktop Laser
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Which does not include the flash disk.

However after running lsusb, the device suddenly appears in Nautilus - the lsusb command appears to trigger recognition of the device. If I run lsusb a second time now, I get the following output:

Code: Select all

Bus 001 Device 005: ID 0ef5:2366 PointChips Flash Disk
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 046d:c517 Logitech, Inc. LX710 Cordless Desktop Laser
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Which now includes the flash disk as Device 005.

If I eject the disk, then remove and reinsert it, the same problem occurs. It will not be recognised until I run lsusb. After running lsusb, it functions normally.

This has been reported previously as an Ubuntu bug #242163 on Launchpad, however no-one has suggested a solution or workaround. Is anyone else experiencing this behaviour, and have you found a solution?

Thanks heaps j-mi, I did a load of searching before posting (as always) and have no idea how I missed those, must have used incorrect keywords.
:oops:

Unfortunately though none seem to have isolated the cause of the problem, and it's a bit of a deal-breaker issue on a modern machine. Bother. I'll have to keep fiddling and try some of the minor tweaks suggested in those threads. If anyone has any other suggestions I'd be most grateful.
