Subject: USB mass storage fails to register on kernel 2.6.32
Hi there,
I have a Samsung Story external USB-2.0 1.5TB drive that fails to
detect as a device in more recent kernel versions. 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@...hera) (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

<3>[ 245.862496] usb 1-10: unable to read config index 0

<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
