/dev/cu.usbserial-FTWWMAIP is already in use by another process #312

Open davesag opened 11 years ago

davesag commented 11 years ago

I just upgraded from 3.5.0 to 3.5.1 (when will I learn!) and now when I try to run bfgminer (using a BFL asic box) I get /dev/cu.usbserial-FTWWMAIP is already in use by another process and then it reverts to the GPU instead of using the BFL box.

I've tried restarting, shutting down and unplugging the BFL box, etc etc to no avail.

I'm heading away for a month and would love to fix this before I go so I can leave my system mining.

System - OSX 10.9, bfgminer was installed via homebrew and upgraded via homebrew.

running it with the following command (which worked fine in 3.5.0) bfgminer -o http://mypoolurl:8332 -u worker.name -p password -S /dev/cu.usbserial-FTWWMAIP

Okay I got this to work again as follows:

changed my startup command to bfgminer -o http://mypoolurl:8332 -u worker.name -p password -S bfl:/dev/cu.usbserial-FTWWMAIP

Not really sure why that fixed it, but it did. yay

Can you try disabling the other drivers (at configure) one by one to identify which one is causing the problem?

davesag commented 11 years ago

That's the only relevant driver in my system. No other devices plugged into my Mac apart from keyboard and mouse.

luke-jr commented 11 years ago

I'm referring to the BFGMiner drivers. --disable-icarus for example.

davesag commented 11 years ago

well it's working fine now and I have a mountain of work to do so I'd rather not dive into it sorry. When you say --disable-icarus that makes me suspect I'd spend an hour wading into documentation to solve something that's already solved. Don't mean to seem ungrateful but I have deadlines to meet.
