CANable CAN adapters

I’ve used adapters from CANable in the past when I needed to do CAN Bus testing. Unfortunately, their adapters have not been in stock recently, so I ordered a few clones off eBay:

They appear to come installed with firmware that exposes the device as a native CAN controller (vs a serial port):

[430148.232094] gs_usb 5-3.3:1.0: Configuring for 1 interfaces
[430216.983448] usb 5-3.5: new full-speed USB device number 29 using xhci_hcd
[430217.089189] usb 5-3.5: New USB device found, idVendor=1d50, idProduct=606f, bcdDevice= 0.00
[430217.089194] usb 5-3.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[430598.396465] IPv6: ADDRCONF(NETDEV_CHANGE): can0: link becomes ready

[430635.640604] NET: Registered PF_CAN protocol family
[430635.645971] can: raw protocol

Perhaps the CandleLight firmware?

At any rate, can0 and can1 network devices showed up and appear to work:

sudo ip link set can0 type can bitrate 1000000
sudo ip link set can1 type can bitrate 1000000
sudo ip link set up can0
sudo ip link set up can1

In one terminal:

candump can0
  can0  123   [8]  01 23 45 67 89 AB CD EF

In another terminal:

cansend can1 123#0123456789abcdef
