Folks,
I'm using a PCAN-USB adapter, and it seems to have a lot of trouble
under medium load. I'm getting these urb aborted messages.

As I run the same hardware here it is very likely that you have a faulty
CAN bus setup with
- wrong bitrate setting / sample points / etc
- wrong or no termination
- missing or wrong configured (other) CAN nodes
I added the maintainer of the PEAK USB adapter (Stephane) to the
recipient list.
Having the linux-can mailing list and Stephane in the recipient list is
sufficient to answer the above details.

Is there anything that can be done about this? This is very
frustrating because it makes the USB adapter very difficult to use as
a reliable partner of an embedded CAN device.
I'm using Ubuntu with 5.4.0-107-generic. Any help would be appreciated.
