There are a lot of changes since then, including some Renesas host vendor specific quirks. Logs show transaction errors on endpoint 0, probably while reading descriptors during enumeration. I'd recommend trying with a more recent kernel such as 6.7, If that also fails the we can take a closer look at it. If 6.7 works but you need to run a 4.4 kernel for some reason, then I'd suggest bisecting the kernel until the right fix is found, and backport it. lsusb is a part of usbutils.
