I took delivery of a nifty new laptop here at Chez Tittel late last week. Among the zillions of other things going on around here, I’ve been fooling with this machine since it arrived. This loaner laptop poses weird USB situation, though: I get faster throughput from its USB-A 3.2 Gen1 port than either of its USB4 Type-C/Thunderbolt 4 ports. Throughput is about 10X faster on the USB-A port than on USB-C. That’s not how it’s supposed to work. Go figure!
Driver Issues Explain How Loaner Laptop Poses Weird USB Situation
Once I realized what was going on. I jumped into Device Manager. Sure enough there’s an issue with the ThinkPad Thunderbolt Retimer Firmware. Whaddya bet this could impact USB-C/Thunderbolt 4 timing?
And then, things get more interesting. Lenovo Vantage thinks the firmware update is already installed. Device Manager shows “Firmware update was unsuccessful.” Attempts to uninstall/reinstall don’t work, and manual installation of the downloaded firmware package N32TT02W.exe from Lenovo Support don’t work either.
I need some firmware juju. So I’m contacting Lenovo Support to see what they can tell me. I’ll admit I got fooled when Vantage told me the update was installed (and didn’t check DevMgr until later). Now, it looks like I’ll have to roll the machine back to Windows 10 so I can make sure the update gets properly applied. And then, I’ll roll forward again to Windows 11. Just another day in the life, here in Windows-World!
Checking Updates, Post Install
It hasn’t eluded me that checking the firmware install before upgrading to 11 would have been a peachy idea. I’m not one to rush into such things normally. But I wanted to see how the new PC would work with the new OS. I guess I’m starting to understand there’s at least one good reason why Lenovo didn’t send me the device with Windows 11 already installed.
As I look around the Lenovo site, I see they have Thunderbolt drivers for Windows 11 aplenty. It’s just that they don’t have one for my X1 Carbon Gen 9 laptop just yet. Live and learn, dear readers: that’s why I’m going to try to do.

HI, got a similar situation this morning. A Recommended Lenovo update for the thunderbolt 4 firmware maimed it in the same way…
Did you end up returning it, or found a fix?
I performed an in-place repair install and it did the trick for me. Don’t know what went wrong with the original drivers, but that seemed to take care of it. HTH, =Ed=
