USBest manufactures a wide variety of USB flash drives and storage devices. The UTSCSI application is said to be related to the PQI Group's U510 credit-card shaped USB device first introduced in 2006. Some USB flash drives come with an installation CD and this is said to install when the CD does. It uses very little memory yet seriously hinders or slows PC performance without having a clearly evident function. USBest is evidently in mainland China, (their website has no location information), whereas PQI was in Taiwan. Milestones reported on PQI's website end at 2012 and USBest's website says it is introducing a new card-type drive so they may have acquired PQI.
