Hi, There has been a recent fix to the EHCI driver, which might affect Mass Storage when short transfers are used. Also someone else has pointed out that certain VIA chipsets have an IRQ "bug" requiring the need for a software callout to restart the EHCI interrupt handler. This is not yet patched, hence I don't know if this is a real issue. http://svn.freebsd.org/viewvc/base?view=revision&revision=197682 Is your code from after 1st of October? --HPS
