Hi, I have a cheap USB hard disk enclosure with a rather sad IDE disk in it. It all seems to work fine, once I get Linux to recognize the disk. The problem is that if I power on the enclosure while it's plugged into my USB hub, it looks like Linux times out and decides to ignore the device.
If I just power it on and leave it for a bit, and then plug it in, it seems to work fine. I'm using a rather old 2.6.11.7 kernel. Will upgrading help? It seems like the problem is just that Linux gives up on the device much too early. Alternatively, is there some way to ask Linux to scan this device again? Here's the device powering on while plugged in: usb 3-1.3: new high speed USB device using ehci_hcd and address 9 scsi2 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 9 usb-storage: waiting for device to settle before scanning usb 3-1.3: reset high speed USB device using ehci_hcd and address 9 scsi: Device offlined - not ready after error recovery: host 2 channel 0 id 0 lun 0 usb-storage: device scan complete Here's me pulling the cable out and plugging it back in after it's been on for 30 seconds: usb 3-1.3: USB disconnect, address 9 usb 3-1.3: new high speed USB device using ehci_hcd and address 10 scsi3 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 10 usb-storage: waiting for device to settle before scanning Vendor: USB 2.0 Model: Storage Device Rev: 0111 Type: Direct-Access ANSI SCSI revision: 00 sdc : very big device. try to use READ CAPACITY(16). sdc : READ CAPACITY(16) failed. sdc : status=0, message=00, host=5, driver=00 sdc : use 0xffffffff as device size SCSI device sdc: 4294967296 512-byte hdwr sectors (2199023 MB) sdc: assuming drive cache: write through SCSI device sdc: 4294967295 512-byte hdwr sectors (2199023 MB) sdc: assuming drive cache: write through sdc: sdc1 Attached scsi disk sdc at scsi3, channel 0, id 0, lun 0 Attached scsi generic sg2 at scsi3, channel 0, id 0, lun 0, type 0 usb-storage: device scan complete Thanks, -J _______________________________________________ Linux-usb-users@lists.sourceforge.net To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
