Full kmsg details are below. Note that a USB thumb drive works fine on my system. Older kernels work fine with the Samsung also. In terms of which version of the kernel this stopped working, this I don't know. uname -a gives: Linux version 2.6.32-23-generic (buildd@rothera) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #37-Ubuntu SMP Fri Jun 11 07:54:58 UTC 2010 My kmsg output when plugging in the drive is as follows: <6>[ 244.624034] usb 1-10: new high speed USB device using ehci_hcd and address 3 <3>[ 244.780033] usb 1-10: device descriptor read/64, error -32 <3>[ 245.036030] usb 1-10: device descriptor read/64, error -32 <6>[ 245.252038] usb 1-10: new high speed USB device using ehci_hcd and address 4 <3>[ 245.862496] usb 1-10: unable to read config index 0 descriptor/start: -71 <3>[ 245.862615] usb 1-10: chopping to 0 config(s) <3>[ 245.979496] usb 1-10: string descriptor 0 read error: -71 <4>[ 245.980413] usb 1-10: no configuration chosen from 0 choices When plugging in my thumb drive I get the expected results: <6>[ 135.216034] usb 1-10: new high speed USB device using ehci_hcd and address 2 <6>[ 135.352726] usb 1-10: configuration #1 chosen from 1 choice <6>[ 135.410021] Initializing USB Mass Storage driver... <6>[ 135.410186] scsi6 : SCSI emulation for USB Mass Storage devices <6>[ 135.410460] usbcore: registered new interface driver usb-storage <6>[ 135.410466] USB Mass Storage support registered. <7>[ 135.414677] usb-storage: device found at 2 <7>[ 135.414682] usb-storage: waiting for device to settle before scanning <7>[ 140.412291] usb-storage: device scan complete <5>[ 140.414270] scsi 6:0:0:0: Direct-Access USB Flash Disk 1100 PQ: 0 ANSI: 0 CCS <5>[ 140.417527] sd 6:0:0:0: Attached scsi generic sg3 type 0 <5>[ 140.419744] sd 6:0:0:0: [sdc] 1014784 512-byte logical blocks: (519 MB/495 MiB) <5>[ 140.424490] sd 6:0:0:0: [sdc] Write Protect is off <7>[ 140.424500] sd 6:0:0:0: [sdc] Mode Sense: 43 00 00 00 <3>[ 140.424506] sd 6:0:0:0: [sdc] Assuming drive cache: write through <3>[ 140.428511] sd 6:0:0:0: [sdc] Assuming drive cache: write through <6>[ 140.428631] sdc: sdc1 <3>[ 140.494141] sd 6:0:0:0: [sdc] Assuming drive cache: write through <5>[ 140.494261] sd 6:0:0:0: [sdc] Attached SCSI removable disk usb-devices output is as follows: T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh=10 D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=1d6b ProdID=0002 Rev=02.06 S: Manufacturer=Linux 2.6.32-23-generic ehci_hcd S: Product=EHCI Host Controller S: SerialNumber=0000:00:02.1 C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub T: Bus=01 Lev=01 Prnt=01 Port=09 Cnt=01 Dev#= 2 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 0 P: Vendor=04e8 ProdID=5f06 Rev=00.00 S: Manufacturer=JMicron S: SerialNumber=0000002CE09310500626 C: #Ifs= 0 Cfg#= 0 Atr= MxPwr= cat: /sys/bus/usb/devices/usb1/1-10/1-*:?.*/bInterfaceNumber: No such file or directory cat: /sys/bus/usb/devices/usb1/1-10/1-*:?.*/bAlternateSetting: No such file or directory cat: /sys/bus/usb/devices/usb1/1-10/1-*:?.*/bNumEndpoints: No such file or directory cat: /sys/bus/usb/devices/usb1/1-10/1-*:?.*/bInterfaceClass: No such file or directory cat: /sys/bus/usb/devices/usb1/1-10/1-*:?.*/bInterfaceSubClass: No such file or directory cat: /sys/bus/usb/devices/usb1/1-10/1-*:?.*/bInterfaceProtocol: No such file or directory /usr/bin/usb-devices: line 79: printf: (none): invalid number I: If#= 0 Alt= 0 #EPs= 0 Cls=() Sub= Prot= Driver= T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh=10 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=1d6b ProdID=0001 Rev=02.06 S: Manufacturer=Linux 2.6.32-23-generic ohci_hcd S: Product=OHCI Host Controller S: SerialNumber=0000:00:02.0 C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub I think this might be a related problem: http://quantan.blogspot.com/2010/03/ubuntu-1004-lts-b1-dan-usb-modem-gsm.html I will be unsubscribing from these lists after sending this bug report, so please contact me directly if you need more info at paulsheer at gmail -paul -- 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
