I NEED HELP! PPLLEEEAAASSEE!
I have been trying to connect to my 72V 100A Sabvotron controller for almost a month!
My windows 10 laptop gives me a "Device descriptor request failed".
I have ran every diagnostic tool and even had to disengage windows control over unsigned drivers (ch341.exe).
It seems windows views the controller as a device rather then a serial connection via USB.
The red light is on on the contoller and green light stays off.
The throttle, ignition and speed control all work fine (no load).
I have tried three usb cables and spent countless hours in front of my laptop.
I will be happy to donate to charity or even your pay pal account if you can solve my issue. I am that desperate!!!!
Cheers and thank you!
2 possible workarounds:
The easiest: just find or borrow a computer with win7 from a friend/family member. It shouldn't be very hard to find.
A bit more expensive: purchase the Bluetooth dongle and use your phone to set up the controller.
Windows 10 is among the worst thing that happened to computers in history. Nothing ever works fine, I have countless issues at my work because of this piece of trash OS.
