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.
