I did exactly the same thing (used CW ROM on the U8652, and accepted the version number it came up with.) As Lebo said, you can still install CWM using the instaladot.bat without having to do the power and volume thing.
I think what I did to get the Instaladot.bat to continue past the 'waiting for device' was to re-install the 'ADB' drivers. I had a copy from my phone, but I think you can also get them here;

Several times, WinXP would prompt me through the new hardware wizard when I plugged in the phone. I had to install the adb driver many times, even though it was already installed.
Each time it was working properly, I would see "ADB something device" in the list of "safely remove hardware" entries.
Also (but I'm not sure this confirms if it means it's detected), if I opened a command prompt and navigated to the adb.exe, a "adb devices" would correctly list the device instead of listing a line that says ????????.
