Genesys USB Storage Problem

[John Morgan Salomon]

Hi all,

I've installed 4.9-RELEASE without major problems on a Thinkpad X31.

I'm trying to access my old 20GB IBM laptop IDE drive via an external
USB drive case, but keep getting the well-known

Nov  1 19:15:55 asparagus /kernel: umass0: BBB reset failed, IOERROR
Nov  1 19:15:55 asparagus /kernel: umass0: BBB bulk-in clear stall failed, 
IOERROR
Nov  1 19:15:55 asparagus /kernel: umass0: BBB bulk-out clear stall 
failed, IOERROR

every 5 seconds.  The drive has 5 filesystems on it (it was the boot disk
for my last laptop);  I can mount and read the root filesystem as 
/dev/da0s1a.
All others (/dev/da0s1e and onwards) give me the IOERROR.  I can 
occasionally
mount them, and list files, but copying them creates empty files, or times
out.  I am not 100% sure that the drive itself is not physically damaged,
as it will not in the new laptop.

I've tried to add the following to /usr/src/sys/cam/scsi/scsi_da.c 
(although
to be honest, I am not entirely sure what I'm doing here):

         {
                 {T_DIRECT, SIP_MEDIA_FIXED, "GENESYS", "*", "*"},
                 DA_Q_NO_SYNC_CACHE
         },

Here's all the USB-relevant boot messages:

Any help is greatly appreciated.
