   Alright...drop #6 works fine here, in fact, with /S:1 setting my USB   
   throughput    
   increases to about 12 MB/s...which is fairly nice compared to the IBM driver's    
   5MB/s speed. Coincidentally, the /S:4 setting equals the IBM driver's    
   performance.   
      
   Here is the machine specific info:   
      
   1) kernel - 14.104a_SMP   
   2) 1 CPU - 4 cores, running SMP with '/APIC' parameter   
   3) ACPI not in use   
   4) 5 OHCI & 2 EHCI controllers   
   5) USB entries in CONFIG.SYS:

   6) HANG specifics: the boot actually freezes regardless of whether USBEHCD.SYS    
   is loaded, right after the "VirtualBox.org Support Driver for OS/2 version    
   1.5.51_OSE" (VBoxDrv.sys) is loaded. ALT-F2 doesn't show anything else...it's   
   a    
   HARD freeze, CHKDSK kicks in on reboot. Keyboard (PS/2) is non-responsive,    
   CTRL-ALT-DEL does not work. "LEGACY" support is enabled in BIOS...otherwise my    
   2Gig thumbdrive is not recognized.   
      
   Now...if I disable 'Legacy Support' in BIOS the boot does complete, but by the    
   time the Desktop comes up it's pretty much non-responsive...it's as if there   
   is    
   a tight loop somewhere that's not even accepting any of my mouse clicks or    
   keyboard inputs. Eventually I am able to reboot (only because I have CAD   
   Handler   
   installed though)...   
      
   7) where should I submit the PCI scan? email to you Lars, or post here? (sort   
   of   
   a lengthy output)
