Comment 7 for bug 555262

I noticed there isn't the same behavoir for all the USB pendrives. For example a Kingston 512 MB (from lsusb -> Bus 001 Device 019: ID 0930:6533 Toshiba Corp. 512M Stick) has this problem, while a Sandisc 8GB (Bus 001 Device 020: ID 0781:5406 SanDisk Corp. Cruzer Micro 1/2/4GB Flash Drive) doesn't. Unfortunately the pen with the problem isn't mine so I'll try to provide more informations as possible about this device
