Hi, I'm having problems getting a USB Mass Storage Device (a fairly generic
Compact Flash card reader) to work in Linux (Mandrake 8.1 with 2.4.8 kernel).
When devfs is set to mount at bootup, there is no device with the name,
/dev/sd*, while with devfs set to unmount (as was suggested in a posting I
saw on usenet) it has tons of the /dev/sd* devices, but none seem to actually
do anything. When I try to mount any of these devices it says "mount:
special device /dev/sda1 does not exist".
The device shows up in /proc/scsi/usb-storage-0/1 as:
Host scsi1: usb-storage
Vendor: Unknown
Product: USB Storage Device
Serial Number: None
Protocol: Transparent SCSI
Transport: Bulk
GUID: 05e307000000000000000000
Attached: 1
However, it is not listed in /proc/scsi/scsi, which just lists my cd burner.
I have scsi_mod, sd_mod, usb-storage, usb-uhci, usbcore, and ide-scsi all
listed in lsmod (among others of course, but those seem like they might be
relevant). I'm not sure exactly what to look for in /proc/bus/usb/devices,
but here are some of the lines surrounding the line about the usb-storage
device:
I: If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=01 Prot=02 Driver=usb_mouse

D: Ver= 1.00 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=0000 ProdID=0000 Rev= 0.00
I have tried rebooting with the card in the slot but it does not seem to
change anything. Anyone have any ideas? (If you could reply to my e-mail
address in addition to the list that'd be helpful, thanks).
