18.3 Problem USB devices
Not all USB mass storage devices work in the EFI environment. A cursory pass/fail test was done with a
sampling of advertised USB devices to determine which products can be used and which ones should be
avoided for use as a SysCon key. The following table is provided as a guide.
Passed test Cyclone Flash Key 128 MB, Edge DiskGo 128 MB, PNY Attaché 512MB, Memorex Travel Drive
256MB, SanDisk MiniCruzer 256 MB, SanDisk MicroCruzer 256 MB
Failed test Sony MicroVault 256MB, MicroAdvantage Quick Drive 128 MB
Not run Lexar Jump Drive Secure - disabled in EFI
Note: PNY and Memorex runs noticeably faster than Cyclone, or SanDisk MicroCruzer(slowest).
