Using an Eaton Evolution S 3000 (usbhid-ups) 2.6.0 on FreeBSD 7.3.
After checking the debug log for an unrelated reason I saw that it
was being swamped by the following message:
The USB stack in FreeBSD prior to 8.0 did not lend itself to being
precisely controlled from userspace by libusb. It sounds like you are
seeing slightly different problems than I saw while trying to make
tripplite_usb work under FreeBSD, but the common symptom was the
interrupt endpoints. (FreeBSD prior to 8.0 seems to poll the endpoints
more frequently than userspace code reads from them, and I often saw
partial packets dropped when the buffer filled up.)
That was kind of what I'd read. Unfortunately I'm stuck with a pre 8.0
release for the moment due to ISDN.
How do things work if you add the "pollonly" option to the
configuration file?
I've just tried this, and the USB debug messages stopped on restart.
Really appreciate the help.
Many thanks,
John
