USB Tools homepage updated

Welcome to USB Tools homepage

There are useful tricks and tips from Robert Lalla there, for example how to improve USB 2.0 read performance (Common USB FAQ).

Read the feedback from testers:

  • User 1: With that patch I can improve read speed of large files from a high performance USB stick (Buffalo Firestix "R") from 16MB/s upto 32MB/s on an Intel dualcore system or upto 25MB/s on an older AthlonXP/VIA system. For comparision: Manufacturer says "read 32MB/s" and independent benchmarks from computer magazines on Windows say 25MB/s or 27MB/s. Unfortunately that patch does not help for write speed. I still measure 3.5MB/s, which is way below manufacturer's 27MB/s write specification, or results from other OS.
  • User 2: Intel ICH8: I had performance: 3 MB/s, now I have 11.5-12..13
  • User 2: nVidia chipset - no changes
  • User 2: Intel P5B-VM 10 MB/s up to 30Мб!!!!

Please send us source code, links to USB tools and applications which are using USBCALLS.

Please inform us if you are supporting industrial USB hardware via USBECD driver.
