Bug Description

I have obtained a 'pentadrive' pentagram usb memory stick (256MB) that is not working properly on 2.6.15. The device is recognized as two separate mass storage devices, both of which fail with 'medium not found' on any operation.

The device does work on OS X and Windows and seems to have two partitions (or is detected as two devices, I'm not familiar with those systems enough to tell). One partition contains a small exe file (about 1MB of totall space), the other has the remaining advertised capacity.

This log actually shows that two devices are detected. After first run the kernel has become unstable and I had to reboot to get that result again.
