[Severity: Medium]
Are the vendor and device IDs for the ATK VXE R1 SE+ swapped here compared
to their definitions?

In hid-ids.h, USB_VENDOR_ID_ATK is grouped with the WIRED device ID, and
USB_VENDOR_ID_ATK_ALT is grouped with the DONGLE device ID. However,
pulsar_table assigns the DONGLE ID to the regular vendor ID and the
WIRED ID to the ALT vendor ID.

Could this prevent the driver from properly binding to the ATK VXE R1 SE+
hardware?
