CANUSB Adapter: How to Check & Test It

Hi.

"Could you please tell me if it's possible to test CAN adapters without connecting them to a car? I have electronic modules for Audi, Ford, Lexus/Toyota, Nissan, and BMW. I connected these modules to the CAN adapters, but I didn't get any results."
When I send the signal to the CAN adapter connected to the PC, I observe it on the CAN bus using an oscilloscope.

It turned out that starting the CANUSB adapter worked. =))))))
"bit CKDIV8 was set. Everything is working normally. I'm confused about the need to set this bit because it wasn't mentioned in the device documentation. Thank you very much for your website =)"
