Bug ID: 214173
Summary: Built-in Renesas uPD720202 fails to initialize on
Thinkpad T14 AMD
Product: Drivers
Version: 2.5
Kernel Version: 5.13.12
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: USB
Assignee: [email protected]
Reporter: [email protected]
Regression: NoAfter doing a series of upgrades on a dual-boot Thinkpad T14 AMD (comprised of Windows driver/firmware upgrade and linux kernel upgrade), the Renesas USB 3.0 doesn't seem to get initialized anymore, timing out on initialization.

This is a notable regression to the previous laptop's state where this got correctly initialized:

Most notably, this renders the laptop's built-in webcam unusable (not showing on the USB bus). There's anecdotal evidence that installing a package containing older firmware resolves this issue (i.e.
https://forums.lenovo.com/t5/Other-Linux-Discussions/No-camera-on-thinkpad-P14s-AMD/m-p/5090434),
but since a lot of data indicates that the firmware is actually located in ROM (and maybe RAM). Since this is a dual-boot system, I'm being a bit cautious with not using an older version if Windows might expect a newer version already.
I'll be happy to do some testing if needed, assuming there's no chance of accidentally bricking the laptop.

[Bug 214173] Built-in Renesas uPD720202 fails to initialize on Thinkpad T14 Gen 1 AMD

--- Comment #1 from Milan Plzik ([email protected]) --- After doing some more testing, it turns out that even the dual-boot windows wasn't able to use the USB controller correctly -- apparently there was a damage to the EEPROM of the USB controller (first 0x84 bytes of the firmware were followed by zeroes). Using a [firmware upload tool](https://github.com/markusj/upd72020x-load) I was able to test and re-upload correct firmware.
