[SOLVED] Ugee M708 stopped working

Roken · 2016-12-17 11:43:08

I can't say for sure exactly when this happened, but my Ugee M708 gfx tablet has become completely unresponsive. It was working just fine last time I used it, and to rule out a H/W fault I tested on an old Mint liveDVD where it worked.

By unresponsive, I mean there's absolutely nothing. Not even pointer movement.

Kernel modules are loaded:

lsmod | grep uclogic
hid_uclogic            16384  0
hid                   114688  4 hid_generic,usbhid,hid_kye,hid_uclogic
usbcore               208896  17 uvcvideo,dvb_usb_af9015,usbhid,snd_usb_audio,usb_storage,ehci_hcd,ohci_pci,usblp,xhci_pci,snd_usbmidi_lib,dvb_usb_v2,btusb,uas,ohci_hcd,hid_uclogic,xhci_hcd,ehci_pci

xinput sees it

and dmesg knows when it's disconnected and reconnected:

Any ideas?

TIA

EDIT: Did an xev test - absolutely nothing. It's like it doesn't exist.

OK, this gets stranger. I downloaded the lastest Mint DVD and booted. The old version has problems with graphics etc. Burned and booted from the DVD. Tablet working. Experimentally, I did a live install of Krita and tested. On Arch, even with the tablet working, I had no pressure sensitivity in Krita. Mint Live DVD, I have pressure sensitivity.

I checked loaded modules on Mint, and there was only hid_generic and hidusb, so I blacklisted the uclogic and kye modules on Arch. No change, it works on a Mint Live DVD, and it may as well not exist on Arch.

Now, it did work before (though as I say, I had no pressure in Krita, which I now know is possible), but I'm very baffled.

Any clues where to look would be gratefully received, now. The only difference not explored that I can think of is kernel (I'm on 4.8.13-1 right now), but since it was loading the modules before I blacklisted them, and since everything else tells me the tablet is there (other than actually doing anything with it) I'm tempted to think not.

A little out of my depth on debugging this now.

I hate to say it, but without even a suggestion or request for more information (and even the request may get me on the right track), this is the only deal breaker I've encountered with Arch. If I can't fix, I may be back on Mint by NY

The latest kernel update appears to have fixed, though it surprises me since I tried a kernel downgrade a full generation with no luck.

Removing all the wizardpen guff seems to have gotten me pressure sensitivity in Krita, too, which is a bonus.
