   Would you be willing to set up tracing and do a system dump if it hangs ?   
   That would allow me to add tracepoints to USBEHCD.SYS at the appropriate    
   places and to analyze from the dump where exactly it hangs.   
      
   If yes, this is how you set up a dump partition:   
   1.) Create a partition > the physical size of your memory and give it a    
   drive letter, say X: (for what follows)   
   2.) Get http://www.os2site.com/sw/drivers/filesystem/dumpfs.zip   
   3.) Copy udumpfs.dll to \os2\dll, copy dumpfs.ifs to \os2\boot, save    
   \os2dump and copy os2dump.hd to \os2dump   
   4.) add "IFS=C:\OS2\BOOT\DUMPFS.IFS" to config.sys (C: being your boot    
   drive). You might need to shift around this statement. I seem to remember it    
   has to be the last IFS   
   5.) add "TRAPDUMP=R0,X:" to config.sys (without quotes)   
   6.) reboot   
   7.) do a "format X: /FS:DUMPFS" to format the dump partition   
   8.) reboot   
      
   You can also read this:   
   http://newsgroups.derkeiler.com/Archive/Comp/comp.os.os2.bugs/20   
   7-09/msg00032.html   
      
      
   Now you are basically set up to do a dump. In order to do a trace you also    
   need to set up tracing. For USBEHCD.SYS, the trace code is 226 (0xE2):   
      
   9.) add "TRACEBUF=512 /M=WRAP,QUEUED,NODTI /D=ALL" to config.sys   
   10.) add "TRACE=ON 226" to config.sys   
   11.) reboot   
      
   Now, when the system reboots and hangs, hit Ctrl-Alt-NumLock-NumLock to    
   initiate a system dump. Let the system dump finish.   
      
   12.) reboot, make sure you boot from a maintenance partition, CD-ROM or    
   alternate config.sys (without USB) so that it does not hang again   
   13.) Now you will need pmdf.exe to extract the trace info from the system    
   dump: do a "\os2\pdpsi\pmdf.exe" to open the dump formatter   
   14.) Do a file open on X:\ and select the dump file   
   15.) You can now enter commands in the command line at the very bottom of    
   the pmdf window. Enter ".ts c:\trace.raw" to save the trace buffer to file    
   c:\trace.raw. I will need this file to have a look at the trace info.
