#63 opencbm hangs after one command on linux

[Anonymous]

Hello!

I recently acquired a ZoomFloppy interface, and have been trying to get it working with opencbm on Linux.

I followed instructions on this page to build, and did so on Fedora 25: https://www.lyonlabs.org/commodore/building-opencbm-on-linux.html

Building and installation works just fine. When I hook up my drive, I can use cbmctrl to issue exactly one command that works. For example, I've been using "cbmctrl detect", "cbmctrl status 8" or "cbmctrl dir 8" successfully. However, if I try a second command, the command never completes and leaves the ZoomFloppy with a flashing LED.

I can do a "cbmctrl reset" to get the LED to stop flashing, and the drive to reinitialize (it spins for a short while), but all subsequent commands still hangs in the same fashion.

If I unplug the ZoomFloppy USB, and then reconnect it, I can again run one successful command, but the second command once again hangs.

I have also installed opencbm using homebrew on my mac laptop, and there everything works as intended, but if possible I'd like to get it working on my linux machine as that's my main workstation.

If there's anything I can do to help fix this, please let me know!

Have been doing some troubleshooting w/ no luck. Also reinstalled box with CentOS 7, but there's the same problem.

Some more info gathered:

Another non-working run, strace output that could maybe provide some hints. The last poll-call timeouts and is called again, over and over. I break from this with CTRL-C, have tried waiting for approx. 15 minutes without anything happening differently.

I have the same problem.
Any Feedback?

Original poster here. I still have the same issue and I don't think this has been addressed by anyone so far.

[Žarko Živanov]

I have similar problem on Ubuntu... All works after restart of the system. But, if I unplug and plug ZoomFloppy, the only command that works is cbmctrl reset, all the others (i.e. cbmctrl dir 8) just hang. With XUM1541_DEBUG=99, the last message is xum1541_wait_status checking for status, and there it stays until I press CTRL+C.

EDIT: opencbm 0.4.99.99, 3.13 64bit kernel on one machine, 4.4 on another, same thing happens.

[Žarko Živanov]

I have tried the older version that worked for me for years, 0.4.99,97, but the same thing happens. Is it maybe something changed in libusb that causes this?

[Žarko Živanov]

I have also tried the oldest libusb I could find (libusb-0.1-4_0.1.12-20), but it is the same. The weird thing is that everything worked for me until about a two months ago....

[Spiro Trikaliotis]

To be honest, I do not have a clue why this happens. There have been reports on Windows as well as Linux so far about this issue.
For some people, changing the USB port (from USB3 to USB2) helped. For others, using a 32 bit version of the OS.
For other, nothing of the above helped.

I am sorry, for the time being, I do not have any idea how to debug this.
One approach might be to check with libusb-1.0 (instead of the no-obsolete libusb-0.1, which is currently used).

[Žarko Živanov]

Spiro, thanks for replying! If you can tell me what/where it may be good I look, I'll gladly help with the debug. My guess is that it is something on PC side (at least it works for me the first time after the reset), if you maybe can put (many?) more log outputs, I can make them for working and non-working case on the same machine and send it. Maybe that could help to narrow it down? I'll try libusb-1.0 in the meantime, and older kernel version also.

[Anonymous]

Original poster again.. if ssh access to a machine with the problem would be helpful to debug it, I could arrange that. Just post here in that case.

[Spiro Trikaliotis]

There was much work on exactly this issue lately by Martin Thierer. Please check v0.4.99.102 again (or commit 07635d9ee).
