I will try building 2.4.21 with usb-storage enabled. In the mean time, I'm getting a lot of the same problems in 2.5.73, which I have built with usb-storage.
Kernel output from usb-storage for 2.5.73 is here: http://bostoncoop.net/adam/temp/kernel-log-2.5 The primary problem now seems to be that the process gets stuck when I try to unmount drive. If I try to halt or reboot, it gets stuck shutting down. Also, the data copied to the drive is sometimes corrupted (causes the player to crash and requires reformatting it). Also, frequently the drive appears to be full when it's not. Although it's a 128M memory card, it usually maxes out around 60-70M. One thing I've noticed is it seems to be write-caching, so that operations copying data to the drive appear to happen much faster than could over a USB 1.1 connection. Sometimes running sync also causes the process to hang. The only way I can successfully reboot or shutdown with umount or sync hung is to remove uhci-hcd. This usually causes umount to segfault, and then I can shut down. If I try to *remount* the drive at this point or reload the uhci-hcd module, the process gets stuck irretrievably. Any suggestions as to how I can pursue this further? --Adam Kessel On Mon, Jun 30, 2003 at 09:58:52AM -0400, Alan Stern wrote: > On Sun, 29 Jun 2003, Adam Kessel wrote: > > > I got this message in kernel 2.5.73 after connecting my Neuros Audio > > player: > > > > ---- > > usb-storage: Vendor: Frontier Labs > > usb-storage: Product: Nex II Digital > > usb-storage: This device (0451,5409) has unneeded SubClass and > > Protocol entries in unusual_devs.h > > Please send a copy of this message to > > <[EMAIL PROTECTED]> > > ---- > > Thanks for the information.
