I have 2 USB plugins. Whether they add Hotplugging or not I don't know. But here they are if it helps:

; Revision:
;
; v1.1 Nov 14, 2003
; - It is now working correctly. Pluging an USB device will cause WinPE to
; enumerate it correctly, no need to "referesh" nor "scan for new hardware"
; Some dlls and files are not applicable to your environment, if so the files
; are made non mandatory eg: =4 rather than =4,,1 which PE checks for file.
; v1.2 Nov 15, 2003
; - Renamed USB-pe.reg to usb.reg - consistent with other apps
; - IEEE1394 removed from usb.reg and made into ieee1394.reg. After registering
; usb.reg you can register ieee1394.reg
; v1.3 Nov 17, 2003
; - Removed extraneous registry entries.
; V1.4 Nov 19, 2003
; - Improved autorun
; - Further cleaning up registry
; V1.5 Nov 22, 2003
; - Uses registry autorun to auto load registry entries so autorun_usb.cmd not required anymore.
; - Moved usb.reg and ieee1394.reg into sub folder REG
; - as of Sept 28, 2004 I am still unable t oconvert this into a proper .inf plugin. This
; is due to inability to convert 0x0a and 0x0b registry entries int WinPE. We have
; to wait unti this is supported by reg2py.py and PeBuilder.
; V2.0 Oct 6, 2004
; - Enhanced - removed dup entries
; - added missing entries
; - usb & 1394 fully hotpluggable and plug&play works ok
; - There is NO need for manual intervention as earlier versions do.
; - Works of with XPe 0.99, not completely tested with XPE 1.0
; XPE 1.0 appears to have altered a few system reg entries.
; V2.1 Oct 13, 2004
; - Minor adjustment to reg entries
; V2.2 Oct 26, 2004
; - Reverted back to copying drivers/programs direct from C:\Windows\system32 ...
; etc so that we will always get the correctversion of the drivers. I recently
; installed a hotfix and discovered new usb & ieee drivers - ousb2ehci etc
; - this is the reason why. It is easy to overlook this fact when you use the
; "Get Files.bat" to copy the files - it is bad programming and waste hdd space.
; - If your windows directory/folder is not C:\Windows\System32\... you
; should replace those entries with your folder name.
; - Removed hardware specific registry entries from "usb&ieee1394base.reg". This
; file now contains the "base" or generic entries for usb&ieee support.
; - To add your specific usb&ieee entries, run the batch file "ExtractMyUSB.bat"
; and it will extract your machine's specific usb&ieee registry and adds to the
; base by creating a new file "use&ieee1394.reg". This is the file that the
; plugin will use. Do NOT delete the "usb&ieee1394base.reg" file. Just keep it
; - Everytime you do a windows update or run a hotfix / security fix, re-run the
; "ExtractMyUSB.bat" again so you will have the correct registry entries
; V2.3 Nov 16, 2004
; - Minor fixup for a couple of registry
; - You must now run (double click) the file "usb & ieee1394 User Reg Extract.bat"
; to extract your specific registry to work with the plugin.
; v2.4a Jan 6, 2005
; - changed the whole script to extract the reg-entries from the user-system
; - modified by cool400
; v2.4b Jan 7, 2005
; - some bugfixes
; - modified by cool400
; v2.4c Jan 8, 2005
; - some more bugfixes, combined both BAT-files
; - modified by cool400
; UBCD4Win version 4/11/05
; - modified by Benjamin Burrows
; - seperated usb & firewire
; - changed back to copying the files from your CD
; UBCD4Win version 11/29/05
; - utilized "4" for all files
; - removed unnecessary entries
; - renamed files because I messed them up!
