There was a change made to the kernel some time ago which caused it = to always use the old scheme first for initializing high-speed USB devices, overriding the value in the old_scheme_first parameter file. It turned out that this change caused problems for some devices, so it was reverted about three years ago. I expect Ubuntu's 5.4.0-33-generic kernel release contains that change and the -37 release contains the reversion; that would explain = what you're seeing. But at least you do have a way to make the device work now. In fact, you o= ught to be able to leave the parameter set to Y permanently; this will work fine with most devices. And if you want to know why the Xone behaves in this strange manner, probab= ly the only way to find out is to ask the manufacturer. --=20 You may reply to this email to add a comment.
