Another SanDisk USB Mini Cruzer problem

[StoneBeat]

execute "lsusb" :
[root at laptop tmp]# lsusb

if you see something like "Genesys Logic, Inc" you have a buggy chip. The 
workaround is do "rmmod ehci-hcd" before you do anything with your buggy 
Disk. If you want a really solution you must use kernel 2.6 and patch. If you 
want more info about the patch ask me.
