lihuiyu xb studio B1 replacement?

Hey guys. after yanking the usb cable my laser is no longer connecting. I have tried replacing the cable , wiring up a new usb component to replace the old one and still no luck. ive traced the the wires back and checked all the wires for damage to no avail. im at a stage now where i think i just need to buy a new control board but cant seem to find that model. are there any other boards that are compatible? I will i kit out my machine eventually but for the mean time i just need it in a working state again. Any direction will be greatly appreciated.
Thanks in advance guys

If it was me, I would go for a better controller.

Controllers do two things: translate code into movement, and control the laser power. Not rocket science.
