...
any ideas?
Not really, but guesses:
The devices should always be available to be opened ... so I'm not sure why that would change.
Make sure the dialup (or whatever privs) are correct as per the old 3.1.1 FPGA-README and reboot
(but I don't think this is the problem, but at least make sure it is all correct anyway)
The 10 minute issue seems to be some sort of BTC problem going around
It was supposed to only be with the new USB code ... but that is the old serial-USB code in 3.1.1 with the CM1 ...
Maybe check it's not using a USB3 port ... coz I'm next to certain at least some problems are USB3 related and nothing to do with whether you use serial-USB or our new direct USB ...
You can't use direct USB fully on that device since it actually has 4 end point pairs on a single USB chip ... so I'd need the device to get the support to work properly.
... and anyone thinking that this is some idea to get people to send me hardware for no reason ... consider that they really don't mine much any more ... just getting the USB driver to work with 8 end points in a single USB chip will take some effort and without the hardware it's a right pain in the ass to try and do it ... and certainly no incentive at all to do it ... as I've said before, I wrote the original chip dividing support for CM1 but I also have/had an Icarus I could test it on with the default divisions back then.
Supporting the FTDI 0x8350 chip is a different issue since I've not had to add multiple end point support for anything yet (though it's a pity that nothing actually uses multiple end points 'properly' i.e. more than 2 end points per mining device ... the CM1 just creates multiple mining devices with the multiple end points)
I'm pretty sure how I'd do it (oddly - it would be like the MMQ) but I'd need the hardware.
I presume it really does have a pair of FPGA attached to each /dev/ttyUSBx ?
If not, and it's only one FPGA per /dev/ttyUSBx then you'll need --icarus-options 115200:1:1 (or 57600:1:1) not sure which speed CM1 is any more
Edit: and use --icarus-timing short
