Weird bios issue with HP Z640 Workstation
I'm having a weird issue with the BIOS on an HP Z640 Workstation. Everytime I try to change a setting on the bios, the tinypilot screen freezes and/or the keyboard stop working. I can't even issue a crtl+alt+del to reboot, I have to power the PC off and on again (using a wifi smartplug).
This HP Bios only allows change by pressing enter... I guess it opens up a popup menu and one selects the option, but I'm not sure since the image freezes.
There's no other way to change a value, like +/-, pgup/pgdow, etc; like in a "normal" bios.
I've checked on the tinypilot and ustreamer is running as it should when that happens... I even tried to restart ustreamer and it does restart, but keeps sending the same frozen image.
I do get an errors on tinypilot dmesg though:
[374328.530887] configfs-gadget gadget: End Point Request ERROR: -108 [374328.541866] dwc2 fe980000.usb: new device is high-speed [374328.561253] dwc2 fe980000.usb: new address 3 [374360.679356] configfs-gadget gadget: End Point Request ERROR: -108 [374360.690341] dwc2 fe980000.usb: new device is high-speed [374360.709671] dwc2 fe980000.usb: new address 3 [374597.920724] configfs-gadget gadget: End Point Request ERROR: -108 [374597.920753] configfs-gadget gadget: End Point Request ERROR: -108 [374624.934568] dwc2 fe980000.usb: new device is full-speed [374644.042845] dwc2 fe980000.usb: new device is high-speed [374644.062221] dwc2 fe980000.usb: new address 4 [374668.078491] configfs-gadget gadget: End Point Request ERROR: -108 [374668.089567] dwc2 fe980000.usb: new device is high-speed [374668.108850] dwc2 fe980000.usb: new address 4
These errors happen a little after I press enter to change a bios value and the image freezes. Not sure if it's related, but maybe it's actually the virtual keyboard device on the tinypilot that is breaking for some reason?
Are you guys aware of this problem by any chance? Is there a fix?

Hello @rhradec - Thank you for posting your question in our Forum.
I'm sorry you are having this issue. I have never seen something like this before. From the messages in
dmesg, it does look like the keyboard is getting disconnected.
Does the virtual on-screen keyboard in the TinyPilot web interface work, when the physical keyboard stops working?
Would it be possible for you to upload logs for me to review? This is how you would upload them: TinyPilot web interface > System > Logs > Get Shareable URL (copy the URL it will give you and paste it in your response).
Is there a chance you could connect a physical keyboard into the target machine, and attempt to type when this issue occurs? So that we can find out if video is indeed frozen, or if it is only the keyboard that stops working. If video is not affected, you should be able to see the screen updating in the TinyPilot web interface.
