Based on work by Rene Engelhard, and reports from others on the LKML list, it looks like a fix is near final.
The following patch adds support for my ScanLogic-based
adapter, OEM'd by H45 technology corp (www.h45.com)
There are other folk who have written about this device,
and as it seems to have the same issue as the device that
Rene wrote his patch for.
I've verified that this patch works for my device. What's needed
is to see if this dev entry could be consolidated with the version
that Rene uses.
Rene -- would you be willing to give this a go? The only thing
that would need to be changed is the Minimum Rev, so that it matched
yours (0x0074)
This patch is originally against 2.4.16, but should apply to 2.5 series.
