hi, i've bought at HP storageworks DAT72 USB external tape drive and i'm trying to make it work under centos 4.2 first the hard facts: os - centos 4.2 kernel 2.4.9-22.0.2.EL MB - MSI 8kn diamong 4gb ram the problem is that i don't see the drive. i'd expected that a device called st0 would appear but it's not the case. watching the messages file when unplugging the device and the replugging it is: Jan 27 13:47:36 miraculix kernel: usb 1-8: new high speed USB device using address 6 Jan 27 13:47:41 miraculix kernel: usb 1-8: control timeout on ep0in Jan 27 13:47:42 miraculix kernel: usb 1-8: device not accepting address 6, error -71 Jan 27 13:47:42 miraculix kernel: usb 1-8: new high speed USB device using address 7 Jan 27 13:47:47 miraculix kernel: usb 1-8: control timeout on ep0in Jan 27 13:47:48 miraculix kernel: usb 1-8: device not accepting address 7, error -71 Jan 27 13:48:16 miraculix kernel: usb 1-7: new high speed USB device using address 8 Jan 27 13:48:21 miraculix kernel: usb 1-7: control timeout on ep0in Jan 27 13:48:22 miraculix kernel: usb 1-7: device not accepting address 8, error -71 Jan 27 13:48:22 miraculix kernel: usb 1-7: new high speed USB device using address 9 Jan 27 13:48:27 miraculix kernel: usb 1-7: control timeout on ep0in Jan 27 13:48:28 miraculix kernel: usb 1-7: device not accepting address 9, error -71 Jan 27 13:49:01 miraculix kernel: usb 1-1: new high speed USB device using address 10 Jan 27 13:49:07 miraculix kernel: usb 1-1: control timeout on ep0in Jan 27 13:49:07 miraculix kernel: usb 1-1: device not accepting address 10, error -71 Jan 27 13:49:07 miraculix kernel: usb 1-1: new high speed USB device using address 11 Jan 27 13:49:12 miraculix kernel: usb 1-1: control timeout on ep0in Jan 27 13:49:13 miraculix kernel: usb 1-1: device not accepting address 11, error -71 but i don't know what it means. the documentation on the drives says the the two drivers usb_storage and st should be loaded and the drive should work out of the box. but it doesn't. i'm loading both drivers after startup using this command: modprobe usb_storage and modbrobe st what am i missing????? any help appreciated. br kim gabrielsen
