I don't use this device often so I don't know if this combination ever worked in previous kernels. I was trying to read a 16GB microSD card. The hub claims to be able to read MicroDrive, SmartMedia, CompactFlash, Memory Stick, Multimedia and Secure Digital. (reading from the label on the device) FWIW 16GB == 16*1000*1000*1000 >From http://www.linux-usb.org/usb.ids: (couldn't find this in the kernel source) 0d7d Phison Electronics Corp. 0240 I/O-Magic/Transcend 6-in-1 Card Reader kernel version 3.6.7 [367851.023224] usb 3-1: new full-speed USB device number 13 using ohci_hcd [367851.180145] usb 3-1: New USB device found, idVendor=0d7d, idProduct=0240 [367851.180145] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [367851.180145] usb 3-1: Product: USB Reader [367851.180145] usb 3-1: Manufacturer: [367851.183145] scsi7 : usb-storage 3-1:1.0 [367852.191812] scsi 7:0:0:0: Direct-Access USB Card Reader 1.01 PQ: 0 ANSI: 0 CCS [367852.199885] scsi 7:0:0:1: Direct-Access USB Card Reader 1.01 PQ: 0 ANSI: 0 CCS [367852.207145] scsi 7:0:0:2: Direct-Access USB Card Reader 1.01 PQ: 0 ANSI: 0 CCS [367852.214146] scsi 7:0:0:3: Direct-Access USB Card Reader 1.01 PQ: 0 ANSI: 0 CCS [367852.216145] sd 7:0:0:0: Attached scsi generic sg2 type 0 [367852.216565] sd 7:0:0:1: Attached scsi generic sg3 type 0 [367852.216565] sd 7:0:0:2: Attached scsi generic sg4 type 0 [367852.216565] sd 7:0:0:3: Attached scsi generic sg5 type 0 [367856.886551] sd 7:0:0:2: [sdd] 1 512-byte logical blocks: (512 B/512 B) [367856.923227] sd 7:0:0:2: [sdd] Write Protect is on [367856.923227] sd 7:0:0:2: [sdd] Mode Sense: 43 00 80 00 [367856.963227] sd 7:0:0:2: [sdd] No Caching mode page present [367856.963227] sd 7:0:0:2: [sdd] Assuming drive cache: write through [367856.987033] sd 7:0:0:0: [sdb] Attached SCSI removable disk [367857.026551] sd 7:0:0:1: [sdc] Attached SCSI removable disk [367857.046033] sd 7:0:0:3: [sde] Attached SCSI removable disk [367857.073217] sd 7:0:0:2: [sdd] No Caching mode page present [367857.073217] sd 7:0:0:2: [sdd] Assuming drive cache: write through [367888.136553] usb 3-1: reset full-speed USB device number 13 using ohci_hcd [367903.259389] usb 3-1: device descriptor read/64, error -110 [367918.479883] usb 3-1: device descriptor read/64, error -110 [367918.705930] usb 3-1: reset full-speed USB device number 13 using ohci_hcd [367933.823216] usb 3-1: device descriptor read/64, error -110 [367949.046547] usb 3-1: device descriptor read/64, error -110 [367949.269880] usb 3-1: reset full-speed USB device number 13 using ohci_hcd [367954.286566] usb 3-1: device descriptor read/8, error -110 [367959.406541] usb 3-1: device descriptor read/8, error -110 [367959.626547] usb 3-1: reset full-speed USB device number 13 using ohci_hcd [367964.643891] usb 3-1: device descriptor read/8, error -110 [367969.760640] usb 3-1: device descriptor read/8, error -110 [367969.863211] usb 3-1: USB disconnect, device number 13 [367969.863211] sd 7:0:0:2: Device offlined - not ready after error recovery [367969.863211] sd 7:0:0:2: [sdd] Unhandled error code [367969.863211] sd 7:0:0:2: [sdd] [367969.863211] Result: hostbyte=0x05 driverbyte=0x00 [367969.863211] sd 7:0:0:2: [sdd] CDB: [367969.863211] cdb[0]=0x28: 28 00 00 00 00 00 00 00 01 00 [367969.863211] end_request: I/O error, dev sdd, sector 0 [367969.863211] Buffer I/O error on device sdd, logical block 0 [367969.863211] sd 7:0:0:2: rejecting I/O to offline device [367969.863211] sd 7:0:0:2: rejecting I/O to offline device [367969.863211] sdd: unable to read partition table [367969.863211] sd 7:0:0:2: [sdd] Attached SCSI removable disk [367969.986545] usb 3-1: new full-speed USB device number 14 using ohci_hcd [367985.106543] usb 3-1: device descriptor read/64, error -110 [368000.333203] usb 3-1: device descriptor read/64, error -110 [368000.553209] usb 3-1: new full-speed USB device number 15 using ohci_hcd [368015.673576] usb 3-1: device descriptor read/64, error -110 [368030.896541] usb 3-1: device descriptor read/64, error -110 [368031.120164] usb 3-1: new full-speed USB device number 16 using ohci_hcd [368036.137539] usb 3-1: device descriptor read/8, error -110 [368038.334981] usb 3-1: device descriptor read/8, error -62 [368038.489866] hub 3-0:1.0: unable to enumerate USB device on port 1 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
