Sometimes when I connect it to one of the several USB ports on my computer, I get this in syslog: {{{ 2009-08-29 17:08:48 KERN: usb hub 32: port 4: new device connected 2009-08-29 17:08:49 KERN: usb error ehci 6: qtd (0x041d4680) error: 0x00080248 2009-08-29 17:08:49 KERN: usb error ehci 6: qtd (0x041d4880) error: 0x00080248 2009-08-29 17:08:49 KERN: usb error ehci 6: qtd (0x041d4a80) error: 0x00080248 2009-08-29 17:08:49 KERN: usb error ehci 6: error while setting device address }}} And, of course, the device is not recognized. If I remove and reinsert it (may need to do it a few times) sometimes it is picked up: {{{ 2009-08-29 17:10:13 KERN: usb hub 32: port 4: new device connected 2009-08-29 17:10:14 KERN: usb_disk: device reports a lun count of 4 2009-08-29 17:10:14 KERN: usb_disk: vendor_identification ""Generic "" 2009-08-29 17:10:14 KERN: usb_disk: product_identification ""USB SD Reader "" 2009-08-29 17:10:14 KERN: usb_disk: product_revision_level ""1.00"" 2009-08-29 17:10:14 KERN: usb_disk: vendor_identification ""Generic "" 2009-08-29 17:10:14 KERN: usb_disk: product_identification ""USB CF Reader "" 2009-08-29 17:10:14 KERN: usb_disk: product_revision_level ""1.01"" 2009-08-29 17:10:14 KERN: usb_disk: vendor_identification ""Generic "" 2009-08-29 17:10:14 KERN: usb_disk: product_identification ""USB SM Reader "" 2009-08-29 17:10:14 KERN: usb_disk: product_revision_level ""1.02"" 2009-08-29 17:10:14 KERN: usb_disk: vendor_identification ""Generic "" 2009-08-29 17:10:14 KERN: usb_disk: product_identification ""USB MS Reader "" 2009-08-29 17:10:14 KERN: usb_disk: product_revision_level ""1.03"" 2009-08-29 17:10:14 KERN: usb_disk: request_sense: key: 0x06; asc: 0x28; ascq: 0x00; }}} And works as expected.
