I went out and picked up a TB display last night to pair with my 2011 mbp. I live in windows about 95% of the time and expected there to be no issues with the basic usb hub built into the display unfortunately that does not seem to be the case. My Apple usb keyboard (also brand new) and dell usb mouse both hang/freeze/work erratically when connected to the back of the display, as does my Jabra pro headset. I can make the behavior 10 times worse simply by using hardware built into the display, such as the facetime camera. If I fire up Lync and start a video chat, my keyboard and mouse become nearly unusable. My basic testing under Lion appears to confirm this is an issue with Apples boot camp drivers as things work fine under OS X. The problem happens both under win7 and win2008r2. No issues with hardware plugged directly into the laptop. The problem appears to be with thunderbolt/drivers as even with no peripherals plugged into the display's usb ports, the facetime camera exhibits the same pauses/lags when used. Pretty crappy release, Apple. Hopefully this can easily be addressed with better drivers.
