Here's what lsusb -v has to say:

        bInterval              10
Device Status:     0x0000
  (Bus Powered)


And the relevant part of $(lsusb -t):
Code:
/:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=ohci-pci/3p, 12M
    |__ Port 1: Dev 2, If 0, Class=Human Interface Device, Driver=, 1.5M

(note the empty Driver= — this is the only device in the output that shows up empty)

According to $(modinfo hid-uclogic), this device is supported:
Code:
alias:          hid:b0003g*v00005543p00000005


eudev isn't autoloading that module though, and manual modprobe doesn't have any effect either. The tablet doesn't show up in /proc/bus/input or /dev/input. Nothing in dmesg, here's all it prints when I plug it in:
Code:
[ 1482.100438] usb 5-1: new low-speed USB device number 3 using ohci-pci
[ 1482.254459] usb 5-1: New USB device found, idVendor=5543, idProduct=0005
[ 1482.254472] usb 5-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 1482.254479] usb 5-1: Product: Tablet WP8060U
[ 1482.254485] usb 5-1: Manufacturer: UC-LOGIC


Running $(usbhid-dump -m 5543) produces this, so it at least recognises it as a HID device:
Code:
005:002:000:DESCRIPTOR         1398305835.958292

 01 09 30 09 31 15 00 26 FF 7F 35 00 46 FF 7F 95
 02 75 10 81 02 05 0D 09 30 26 FF 03 95 01 75 10
 81 02 C0 C0


I'm completely lost at this point. I do have another tablet (hid-waltop) that works fine, shows up in /dev/input, works in X, etc.

Could it simply be because the WP8060U is blacklisted ?
Code:
hid_blacklist[] = {
...
   { USB_VENDOR_ID_UCLOGIC, USB_DEVICE_ID_UCLOGIC_TABLET_WP8060U, HID_QUIRK_MULTI_INPUT },
...
};

Quoted from /usr/src/linux-3.X.Y/drivers/hid/usbhid/hid-quirks.c on, at least, latest X ∈ {4;8;10;11;12;13}

That array isn't well named - reading the rest of the code it appears that flag should make it create *multiple* input devices, not none.

Some more diagnostics:
Code:
# udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent
