Hi Martin,
That error looks interesting. The reason we deleted the old saleae-logic
driver was so that we could get a wider audience of testers for this new
driver, so this is helpful information.
You seem to have found a problem with my CMD_GET_FW_VERSION command. I
noticed something the other day in the firmware that might be relevant, and
I made a patch which I will submit soon.
You do have the git head fx2lafw installed, right? Does this problem occur
on all machines? Do you have more than one type of host controller in your
machine? Do these make a difference?
I'm having a busy couple of weeks, so I don't have much time to look at the
problem for a few days. But hopefully we can track down the problem in the
next few days.
Joel
