The Razer BlackShark V3 and V3 Pro wireless dongles fingerprint the
USB host by its configuration-descriptor read pattern during
enumeration. Unless they see a single full-length (wLength=255)
request like Windows sends, they refuse to bring up the wireless
telemetry relay and battery, charging and EQ state all read back as
zero.
USB_QUIRK_WINDOWS_CONFIG_REQ_SIZE already implements exactly this
behaviour, so just register it for the four BlackShark V3 PIDs:
0x0576 V3 Pro (wired USB-C)
0x0577 V3 Pro (2.4GHz dongle)
0x0579 V3 (wired USB-C)
0x057a V3 (2.4GHz dongle)
Both the dongle and the wired transport enumerate the same firmware
and need the quirk. Verified on 0x057a and 0x0577: with the quirk the
vendor channel answers and battery/charging/EQ read correctly;
without it every vendor GET returns zero.
