Hi, this post is partly a supplement of Francis, Chong Chan Fai's post from Feb 07, 2004. http://www.mail-archive.com/[EMAIL PROTECTED]/msg19771.html
The behaviour is similar, i.e. the attached USB2.0 hardisk fails when ehci_hci module is loaded, but works fine without it (i.e. in USB1.1 mode). Kernel is vanilla 2.6.3. Host hardware is this: 00:1d.0 USB Controller: Intel Corp. 82801DB USB (Hub #1) (rev 01) 00:1d.1 USB Controller: Intel Corp. 82801DB USB (Hub #2) (rev 01) 00:1d.2 USB Controller: Intel Corp. 82801DB USB (Hub #3) (rev 01) 00:1d.7 USB Controller: Intel Corp. 82801DB USB2 (rev 01) And the box containing the hardisk is Genesys GL811_U240B-E (Chronos HD-337-U2) I have attached logs with usb-storage debugging turned on for the failing case (i.e. how it does not work with ehci_hcd module loaded) and for the working case (i.e. without the ehci_hcd module). Please let me know if I can provide any further help in tracking this bug down. Best regards, -- Juhan Ernits
