XP-Pen Star 06C (Diagnostics) #488

Open Fe-Ti opened 3 years ago

Fe-Ti commented 3 years ago

Recently I've got a XP-Pen Star 06C (Note: that's a USB tablet and doesn't work on v10 release).

It's not mentioned in the list of known tablets, so there are some diagnostics attached to the issue (to be correct they were uploaded to Google Drive). Collected diagnostics: Star06C_V2_Diagnostics.zip

P.S. The archive contains several repetitions for pen_coords,pen_buttons and pen_pressure.

P.P.S. I know that tablet does not work in Linux and Windows (except its dial and 6 buttons), but somehow it does work in Haiku and (at least) in one UEFI BIOS. But when I was collecting data, I found some strange magic. After running uclogic-probe with root privileges I discovered that the tablet had begun operating properly. So I'm just curious why such thing happens? (Note: without running uclogic-probe I can see that Debian shows three readable /dev/hidraw* files)

Upd (09.10.2021): It seems that after reading only one string descriptor via libusb_get_string_descriptor() the tablet starts working properly. At least the main part of it.

Upd (02.06.2023): Here is my PR, where I've just added several lines with descriptors. Maybe it will be helpful

Hello, I've recently got a XP-Pen Star 06 tablet. The only difference is that it is wireless whereas yours is cabled. I think the behavior is identical. There is an issue with PR that adds support for this tablet. I wonder, why it does not work. I have the intention to make this tablet "supported".

Hi! Thanks for the reply! Yes, I've read the PR and tried to make similar changes. But, unfortunately, whatever I changed, Star 06C V2 was working incorrectly (it was detected as a touchscreen). So after two or three weeks I gave up on trying to change the source code by myself. Currently I'm using udev for running a shell script, which in turn runs uclogic-probe. It's a kludge, but it works tolerably. (Also I thought to write a user space program for reading input from /dev/hidraw*)

Hello. I too am trying to get the Star 6 Wireless to work with DIGImend. I have tried to build the driver using DKMS on Manjaro - I checked out the tag v10 and then cherry-picked the PR adding support for Star 6, then built this following the instructions in the readme. There were no errors, as far as I could tell. But the Star wasn't detected by xsetwacom --listno matter what I did in the configuration settings. I am going to try the xppen drivers for now, but I want to help add support for the Star 6 Wireless however I can. EDIT: Are there instructions available for ensuring the driver loaded correctly? sudo lsmod | grep hid revealed

hid_uclogic            40960  0
hid_steam              20480  0
usbhid                 65536  1 hid_uclogic
mac_hid                16384  0

the hid_steam is a Steam Controller. I don't know what mac_hid is. I think the other two are DIGImend.

If not, please point me to some reading about how to load the driver correctly after building with DKMS on Manjaro. Thanks :)

I have an XP-Pen Star 06. I'm presuming it's the C version, since it's USB. I'll see how far I can get this to work.

@hendursaga, I've tried to make it work. The easy part is getting the surface and pen buttons to function properly (just add several lines of code like I did in PR). The problem was in getting other buttons and a ring to work. I've tried to poke around, but due to the lack of knowledge I've failed. So I wish you'll succeed better :)
