Worse? That first patch alone should have behaved exactly the same as the
stock kernel, for working devices.

Make sure that you have turned on the USB debugging option in the kernel
configuration. Then post the dmesg output showing what happens when you
try to plug in a normally working device and when you try to plug in the
TRV38 (that's with both patches). Just for good luck, include also the
dmesg output showing what happens when you plug in a working device
using the vanilla driver.
Maybe comparing the different debugging logs will provide some ideas.
