It has JTAG, but it is also 8 pin SPI flash.
I tried clipping to the SPI flash before contacting usbbdm about it, and I ended up bricking one. It had something to do with clicking ID multiple times quickly. Strange thing is, it appeared to erase the entire flash (that shouldn't be possible, right?). I really have no idea what happened..
Anyway, I desoldered the SPI flash and the USBJTAG was easily able to read and write the chip while out of circuit, so I was able to recover almost everything from the issue.
Great to see JTAG support.
