ACK! :-)

3rd party quick look remarks noted, thank you @adrian very nice documentation, my minor remarks / questions noted :-)

On libusb undefined symbol error:

ld-elf.so.1: /usr/local/lib/libhackrf.so.0: Undefined symbol "libusb_get_parent"

It may be due to your 14.4 version. On my 15.1 I do have it:

% nm -D /usr/lib/libusb.so | grep parent
000000000000d600 T libusb20_dev_get_parent_address
000000000000d610 T libusb20_dev_get_parent_port
0000000000012630 T libusb_get_parent

Very cool, thank you @alven :-)

Builds and works fine, thank you :-) We may want to add firmware-bin into the package and /usr/local/share/hackrf/firmware-bin, these are pre-built ready to use firmware images, which should match software version, simple CP would work, please update :-)

Hmm, one thing I noticed here - the uchcom needs to be loaded prior CH343 connection otherwise ucom handles it with errors - I guess these devices should be out of the box handled by uchcom right? :-)

@avg this CH family seems to be RISC-V based devices with some sort of firmware denoted by version.. do you know is it possible to update firmware of these devices or these are OTP to save costs? I just contacted WCH-IC with question if it possible to firmware update and if not what would be the best way to maintain backward compatibility.

I can see this fix is in stable/14 but not in releng. Later man page update showed up.

Just not sure if pkg-plist still needs list of conditional DOCS file list or not anymore :-P

• Thank you @alven :-)
• Builds, packages, installs, deinstalls fine.
• Very nice addition of documentation :-)
• Runs fine.
• Happy New Year 2026.01.1 :-) :-)

Would it be possible to backport this fix to releng/14.2 branch so it lands into next 14.2-p6 update please? I need to rebuild after update while this fix is important and unblocks working with various embedded systems :-) Is it already in 14.3?

Hmm, I am working on this x11/nvidia-driver-devel 575.64.03 right now, but the nv-sglrun clpeak also crashes thus there is no CUDA / OpenCL. But I think its good to provide this updated version for wider audience testing just as the desktop display driver :-)

Very cool! Thanks @junchoon_dec.sakura.ne.jp will try out and report back :-)

very cool :-) maybe optional iso/usb/vm image creation with selectable format would be useful too? :-)

Is there any chance this driver will land into next 14.2-RELEASE-p4? That would come really handy for some existing setups :-)

BIG THANK YOU KEV!! Both UART baudrate and RTS/DTR seems to be fixed now! I can fully flash the devkit with esptool without manual intervention :-)

AMAZING! Big Thank You Kev!! I will be able to verify on Monday :-)

Yup, I provided information "before", now the information "after" and all seems to work fine, the problem is gone, I can flash devkits with CH343 chip, baudrate change seems to work correctly BIG THANK YOU :-)

Hello world :-)

Thank You @wulf :-)

Thank you Wulf IT'S ALIVE!! =)

This patch from Wulf fixes Trackpad on Panasonic Toughbook CF-MX4 - two finger scroll now works fine! TANK U SIR! =)

Hey @wulf , I guess I cannot put anything above tmux? So this does not solve the problem - gestures still does not work even if synaptics is on the second position. I remember the problem was caused because trackpad here is connected to two busses..

Moving all trackpads up, after Intellimouse does not fix the problem. I will now try to move it above the IneliMouse..

Thank you @wulf Im on it :-)

@wulf I had to recompile kernel to 13 stable with that fix for Touchpad to work. Is there any chance this kind of fix can land in upstream? :-)

Hello world :-) Did fix for this land in 13.0? I have just upgraded and my Trackpad does not work with gestures :-(

Hello world :-)
