Problems with umass driver / CF reader

Hi there!

I've got some problems accessing compact flash disks with my laptop using a
USB CF-reader (PQI single slot reader).

I have three CF disks:
- 8 MB labeled by Canon (came with my digicam)
- 64 MB orginal SanDisk
- 128 MB original Toshiba

If I connect the reader with the 8 MB card inserted, I get the following
messages on console (this is actually from syslog, but the messages are the
same):

Apr 15 00:39:22 gimli /kernel: umass0: Genesys Logic USB Storage Device, rev
1.10/1.13, addr 2
Apr 15 00:39:22 gimli /kernel: umass0: Get Max Lun not supported (STALLED)
Apr 15 00:39:22 gimli /kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Apr 15 00:39:22 gimli /kernel: da0: <Generic STORAGE DEVICE 0.01> Removable
Direct Access SCSI-0 device 
Apr 15 00:39:22 gimli /kernel: da0: 650KB/s transfers
Apr 15 00:39:22 gimli /kernel: da0: 7MB (15681 512 byte sectors: 64H 32S/T
7C)
Apr 15 00:39:44 gimli /kernel: (da0:umass-sim0:0:0:0): READ(6)/WRITE(6) not
supported, increasing minimum_cmd_size to 10.

After that, I can successfully mount the drive and access the data on it.


However, if I connect the reader with the 64 or 128 MB card in it, I only
get :
Apr 15 00:39:08 gimli /kernel: uhub0: device problem, disabling port 1

If I connect the reader without any card in it, I get:
Apr 15 00:36:41 gimli /kernel: umass0: Genesys Logic USB Storage Device, rev
1.10/1.13, addr 2
Apr 15 00:36:41 gimli /kernel: umass0: Get Max Lun not supported (STALLED)
Apr 15 00:36:41 gimli /kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Apr 15 00:36:41 gimli /kernel: da0: <Generic STORAGE DEVICE 0.01> Removable

Apr 15 00:36:41 gimli /kernel: da0: Attempt to query device size failed: NOT
READY, Medium not present

OK, if I insert a card after that and do "camcontrol rescan all" I get:
Apr 15 00:35:22 gimli /kernel: umass0: BBB reset failed, IOERROR
Apr 15 00:35:23 gimli /kernel: umass0: BBB bulk-in clear stall failed,

Apr 15 00:35:23 gimli /kernel: (da0:umass-sim0:0:0:0): lost device
Apr 15 00:35:23 gimli /kernel: (da0:umass-sim0:0:0:0): removing device entry
Apr 15 00:35:23 gimli /kernel: umass0: detached
Apr 15 00:35:24 gimli /kernel: uhub0: device problem, disabling port 1


My questions:

- Are there any known problems with specific CF cards or this type of
reader?
- Does anyone has similar problems (perhaps my laptop is fooling me again)?
- What can I try to fix this?

Last but not least:
%uname -a
