Hopefully, this may help someone:
My Windows XP had recurring "ohcusb.sys." which appeared only after restart. AVG Free identified this as Trojan Generic8.LKV. AVG healed it but "ohcusb" returned whenever I did restart. Startup Monitor freeware identified "msmapibx32.exe." which I deleted and "ohcusb" did not reappear. File path for this "ohcusb" was C:\Windows\System 32\drivers\ohcusb.sys.
"System32\msmapibx32.exe." is recognised as harmful. Prevx website has information about it.

Prevx says that OHCUSB.SYS has yet to be classified as safe or unsafe but I found a submission to jotti virusscan where BitDefender identifies it as Rootkit.Buso.A

msmapibx32.exe is harmful.

You should Set a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recent Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "OK".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.

Prevx reports a number of names and pathways for this infection. This is the only one I'm directly familiar with. And, thank you for mentioning the new Restore Point, that is important.
