ScreamerM2 self-disconnect

Open xNarkon opened this issue 5 years ago • 3 comments

Hey @ufrisk!

I have noticed another bug. Probably firmware related, but I'm not sure.

Sometimes the device is disconnecting from the attacker PC, without any error - just disconnecting. After that, I cannot initialize it with VMMDLL_Initialize until I restart the target PC. Do you have any idea what is happening?

I have noticed disconnects yes, you hear the sound. But for me it always reconnects. The initialization fail is a bit strange.

I'll look into the disconnects though. They bother me, but I have been unable to locate the source of them.

@ufrisk how things going? Any progress? Maybe I could help you to debug it, but I'm not sure if this is likely more connected to the software or hardware?

no, not really, I've been away for some days and just got back home. I have some updates related to Hyper-V I need to take care of before really looking into this as well. I'll try one thing quite soon though to see if it works. With a bit of luck it may resolve the issue; otherwise I'll have to look more into this which is likely to take some time.

Meanwhile the old read algorithm may be better: i.e. -device fpga://algo=2

Closing issue due to old age. I believe it may be better now with recent bug fixes, if not chances are it may be something hardware related which I cannot do anything about.
