Hi Unfortunaltely, I had a couple of problems with ehci on usb-storage since my last report. I've applied ehci-hcd micro-patch from David. I use 2.4.21-rc8-ac1 (basicaly equivalent to 2.4.21-ac1 + ehci-hcd micro patch USB wise).
Also there was a patch from David with the subject line: "[patch 2.5.70] ehci, fix qh re-activation problem" Does this problem exist in some form in 2.4? The problems: 1. usb_control/bulk_msg: timeout You probably know what happens when you get this on usb-storage, but anyway: I was running cdrecord/mkisofs to record some files from vfat disk on USB 2.0 to ide cd-r device. I was playing some mp3s from that disk too. cdrecord stopped, xmms stopped, and kernel panicked in vfat kernel module with a lot of I/O errors. I had to umount the disk, rmmod/insmod usb-storage to make it work again. 2. One time, it happened immediately after powering the disk on, without me even mounting it: hub.c: new USB device 00:09.2-1, assigned address 2 usb.c: USB device 2 (vend/prod 0x5e3/0x702) is not claimed by any active driver. Initializing USB Mass Storage driver... usb.c: registered new driver usb-storage scsi1 : SCSI emulation for USB Mass Storage devices usb_control/bulk_msg: timeout last message repeated 2 times scsi: device set offline - command error recover failed: host 1 channel 0 id 0 lun 0 After I reconnected the disk and rmmod/insmod usb-storage, it worked fine. 3. I've noticed that usb-storage doesn't remove the disk from /proc/scsi/scsi (the representation of kernel scsi device list) when the device is disconnected. Because of that, I cannot connect a different hard disk to usb, without rmmod/insmod usb-storage first, and that can be impossible when I have another device on usb-storage that I don't want to stop using. Can this be fixed for 2.4? 4. About possible performance improvement on 2.5 ehci/usb-storage: I've tested with 2.5.71, and I don't see a significant improvement over 2.4. (Both are arround 7.7 MB/s for read, 10 MB/s for write). Disk can do arround 40 MB/s reads on IDE.
