I suggest adding a few convenience macros to make
this a bit shorter and more likely to fit on a single
line without exceeding 80 cols.

Adding something like:

#define us_<level>(us, fmt, ...)				\
	dev_<level>(&us->pusb_dev->dev, fmt, ##__VA_ARGS__)

so these uses become

	us_info(us, "MiscReg03\n", MiscReg03);

which is shorter and more readable.

Also, there's no need to shout in the logs.
These are reported at KERN_ERR level, so using

	us_err(us, "loading SM RW code failed\n")

would be fine.
