32KB sounds like a limit on the single URB size as enforced by usbfs. But if so, it would affect both speeds. Something does not compute about this report. What's the e-mail of the Vuescan guy? EdHamrick Downloaded the latest version of Vuescan (8.4.12). Same problem: Vuescan works through the USB 1.0 port, but fails through the USB 2.0 port. Now running kernel 2.6.19-1.2288.fc5 Tried a different computer: Vuescan works with the Minolta Scan Dual III scanner when connected to a Zonet ZUN2200 USB 2.0 Cardbus PC Card on a Thinkpad 600E also running Vuescan 8.4.12 and kernel 2.6.19-1.2288.fc5. Perhaps this bug is card-specific? The non-working card is a "CTG USB 2.0 Hi-Speed 5-Port PCI Card", Tiger Direct Item No. C184-29554, purchased in November, 2006. This card works well with a variety of devices including an Epson Perfection 1260 flat-bed scanner being driven by Vuescan 8.4.12 - the Minolta Scan Dual III is the only device tried so far that has not worked with it. This problem persists under kernel 2.6.20-1.2307.fc5 This problem is "fixed" by: rmmod ehci_hcd The problem seems to be card-specific. The card in question is a "Cables To Go USB 2.0 Hi-Speed 5-Port PCI Card", item number C184-29554 at Tiger Direct. Replacing this card with an "IOFuture PU520 High-Speed USB 2.0 PCI Host Controller", item number 15-104-216 at NewEgg, caused this and some other strange USB-related problems to go away.
