Zio success with Red Hat 8.0
by Jason Baietto 31 Oct '02

31 Oct '02

Just a quick report that reading from my Zio works with the latest drivers from your cvs on Red Hat 8.0: $ cat /proc/scsi/usb-storage-0/0 Host scsi0: usb-storage Vendor: SHUTTLE Product: SCM Micro USBAT-02 Serial Number: None Protocol: 8070i Transport: SCM/ATAPI GUID: 04e610100000000000000000 Attached: Yes I replaced the Red Hat drivers/usb/storage directory with the code from cvs, used the Red Hat Makefile but modified it to reflect your file names, and removed a #define CONFIG_USB_STORAGE_DEBUG from debug.h. The resulting module installed fine on the pre-built Red Hat 8.0 kernel (2.4.18-17.8.0). It's not clear from reading the source, but it appears that writing to the device should work. I've mounted the /dev/sda1 read/write and attempted to write, but when I "sync" the command hangs and I get the following in /var/log/messages: kernel: usb_control/bulk_msg: timeout last message repeated 4 times kernel: SCSI disk error : host 0 channel 0 id 0 lun 0 return code = 70000 kernel: I/O error: dev 08:01, sector 491 Seems that the only way to release the sync is to unplug the device from the usb port. Should writing to the device work at this time? Take care, Jason -- Jason Baietto jason(a)baietto.com

Dear Herald, Thank you for your help. It works now with some instability but this is largely better than nothing! The unmount poses a lot of problem... I have also summarized my experience with zMate and usbat2 in a web page: http://beagle.montesquieu.u-bordeaux.fr/yildi/divers/zmate.html This could help new users of this software. Thanks to all who contributes to the develomment of this project!
