#18237: Low-speed USB not working on TP-LINK Archer C7 V2
-----------------------------+------------------------
Reporter: martin.p.rowe@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: kernel | Version: Trunk
Keywords: usb |
-----------------------------+------------------------
Getting "device descriptor read/64, error -145" then finally "device not
accepting address X, error -145" in dmesg when connecting a USB1 device to
either USB port on my TP-Link Archer C7 V2.
Some troubleshooting/isolation tests I've checked:[[BR]]
1. Different USB1 device connected, same error.[[BR]]
2. Same USB1 devices tested working with TP-Link TL-WDR4300, Barrier
Breaker reports "new low-speed USB device number XX using ehci-
platform".[[BR]]
3. Connecting a USB2 device works correctly (in attached dmesg log the
USB1 device is connected at boot, later a USB2 device is connected, then
the USB1 device is disconnected and reconnected).[[BR]]
4. USB LED next to the port doesn't illuminate for USB1 devices but does
for USB2.[[BR]]
5. Swapping USB ports does not fix the error.[[BR]]
6. Tried building image without applying ar71xx/patches-3.10/490-usb-ehci-
add-quirks-for-qca-socs.patch and 525-MIPS-ath79-enable-qca-usb-
quirks.patch with same error.
Currently on trunk r43087, but none of the versions I have tested have
fixed the problem, including Barrier Breaker.
The USB1 devices tested were a UPS with USB control interface and a
keyboard. USB2 was a flash drive.
