[SOLVED] Can't see USB cardreader

TiredOfThis · 11-09-2009, 10:19 PM

I'm having trouble seeing a USB cardreader that used to work.

It shows up in lsusb OK:

Code:

[nathan@ebisu ~] lsusb
...
Bus 004 Device 023: ID 0781:b2b3 SanDisk Corp. SDDR-103 MobileMate SD+ Reader

But it doesn't mount at all or show up as a SCSI device:

Code:

[nathan@ebisu ~] cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: ST3400620AS      Rev: 3.AA
  Type:   Direct-Access                    ANSI  SCSI revision: 05
Host: scsi6 Channel: 00 Id: 00 Lun: 00
  Vendor: BENQ     Model: DVD DD DW1640    Rev: BSRB
  Type:   CD-ROM

I appear to have the right modules (plus my usb mouse/keboard work):

Code:

[nathan@ebisu ~] lsmod | grep usb
usbhid                 52528  0
hid                    41136  1 usbhid
ff_memless              8752  1 usbhid
usbcore               195712  4 usbhid,ehci_hcd,uhci_hcd

I see no error messages:

Code:

[nathan@ebisu ~] dmesg | tail
usb 4-1: new high speed USB device using ehci_hcd and address 23
usb 4-1: configuration #1 chosen from 1 choice
usb 4-1: New USB device found, idVendor=0781, idProduct=b2b3
usb 4-1: New USB device strings: Mfr=0, Product=4, SerialNumber=5
usb 4-1: Product: MobileMate SD+
usb 4-1: SerialNumber: 22925

I've tried using another cardreader and an external USB HDD and the same problem happened with all of them.

Advice appreciated.

Thanks,
Nathan

Hi,

what happens if you explicitly add these modules?

Code:

modprobe usb_storage
modprobe scsi_mod

Thanks for the quick response!

Adding those modules seemed to work. I'm not sure why they got unloaded.

Thanks for the help!
