Hi Dan, You may want to take a look at this email from the USB devel archives from a few days ago,
http://marc.theaimsgroup.com/?l=linux-usb-devel&m=104325644015865&w=1 and the full set of patches for this concern are currently posted at bitkeeper http://linuxusb.bkbits.net:[EMAIL PROTECTED]?nav=index.html|ChangeSet@-1d or you can wait for -pre5. Not sure if this address you concern but it's worth a try, BTW your not the only one with USB storage problems, my cd-rw has been broken since 2.4.19-pre3 and the USB users list is rife with various concerns, most of which go unanswered. Good luck. Steve Dan Hensley wrote: > > On Thu, 2003-02-06 at 05:42, Kreider, Carl wrote: > > > > I don't know if I have the same problem as you, but I have had some > > corruption trouble too.
