[Bug 1511511] Re: USB keyboard stops working after pressing extended key
@Alexander, @Taimur: thanks to your comments and efforts, I've managed to make a very basic HID driver for this keyboard. I have tested it against kernel 4.15.0-23-generic with success. Please remove "hid_generic" before loading this module and plugging the keyboard in, so that hid_generic doesn't take on the device. I took some parts from the aziokbd.c driver (by Colin Svingen; https://bitbucket.org/Swoogan/aziokbd/src/f3611717bce078056634bc2312dba2787a433401/aziokbd.c?fileviewer =file-view-default) and made a minimal mapping table between the special keys G1-G6 to F1-F5 and SPACE. this way, the rightmost part of the spacebar (which is labelled as G6) also works as the SPACE key. This is my very first implementation of anything related to kernel code, so expect it to be ugly, buggy and incorrect. Actually, I've found that the kernel oops with a stack trace when the device is disconnected. This is not a problem if you're using the keyboard as usual, but if you're unplugging it (as when debugging with a VM, for example), your machine/VM will become unstable. I hope somebody with better understanding of USB and kernel driver programming will take it and make something good out of this code. If you are interested in evolving this driver and you need me to send you keycodes/debugging output, don't hesitate to contact me. ** Attachment added: "Workaround driver for Cougar 500k keyboard bug" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511511/+attachment/5153716/+files/cougar-500k-0.4.tgz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1511511 Title: USB keyboard stops working after pressing extended key To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511511/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@kaihengfeng, I believe upstreaming the driver is the right thing to do, but I need to learn more about how in-tree drivers are written and submitted. Yes, I will try my best to upstreaming it.

[Bug 1511511] Re: USB keyboard stops working after pressing extended key
I've managed to collect two PCAPNG files, one captured using virtualized Windows 7 and the second directly under Ubuntu 16.04LTS fully upgraded up to date. In both sessions, after initialization I pressed "a" key, then special key "G6". The "a" key makes four packets to be recorded. The "G6" special key generates six packets under Windows and only four packets under Linux (the first two packets that can be seen in the Windows dump never occur in Linux). After hitting "G6", the Windows session is fully responsive. But in the Linux session, the device stops responding until: a) is unplugged, then replugged. b) the USB is connected to the Windows Virtual Machine (VirtualBox), which resets the device and makes it responsive again. In the Windows dump, the last 10 packets correspond to the "a" keypress (4 packets) then "G6" keypress (6 packets). In the Linux dump, the last 8 packets correspond to the "a" keypress (4 packets), then "G6" keypress (only 4 packets). ** Attachment added: "PCAPNG dumps of keypress "a" then "G6" (Windows and Linux)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511511/+attachment/4721381/+files/pcapng_dumps.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1511511 Title: USB keyboard stops working after pressing extended key To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511511/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The keyboard was bought a few months ago and the bug have always been there. I've tried the keyboard both in upgraded systems and in fresh installations to no avail. Following your instructions, I have just tested it right now using the mainline kernel (at the URL you provided) and the bug is still showing, so I proceed with adding the tag 'kernel-bug-exists-upstream'. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1511511 Title: USB keyboard stops working after pressing extended key To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511511/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
