Hello, I've just bought a Dane-Elec zMage Compact Flash Reader/Writer. FWIW, it has a "Certified Hi-Speed USB" sticker on the box, and underneath the sticker it says "USB 2.0 compatible".
The problem is that with ehci-hcd it fails: Kernel 2.6.9: dmesg> usb 1-3: new high speed USB device using address 2 dmesg> usb 1-3: control timeout on ep0out dmesg> ehci_hcd 0000:00:10.3: Unlink after no-IRQ? Different ACPI or APIC dmesg> settings may help. dmesg> usb 1-3: control timeout on ep0out dmesg> usb 1-3: device not accepting address 2, error -110 Kernel 2.6.10-rc2 (as suggested by Alan Stern): dmesg> hub 1-0:1.0: state 5 ports 6 chg ffc0 evt 0010 dmesg> ehci_hcd 0000:00:10.3: GetStatus port 4 status 001803 POWER sig=j CSC dmesg> CONNECT dmesg> hub 1-0:1.0: port 4, status 0501, change 0001, 480 Mb/s dmesg> hub 1-0:1.0: debounce: port 4: total 100ms stable 100ms status 0x501 dmesg> ehci_hcd 0000:00:10.3: port 4 high speed dmesg> ehci_hcd 0000:00:10.3: GetStatus port 4 status 001005 POWER sig=se0 PE dmesg> CONNECT dmesg> usb 1-4: new high speed USB device using ehci_hcd and address 16 dmesg> usb 1-4: khubd timed out on ep0in dmesg> ehci_hcd 0000:00:10.3: port 4 high speed dmesg> ehci_hcd 0000:00:10.3: GetStatus port 4 status 001005 POWER sig=se0 PE dmesg> CONNECT dmesg> usb 1-4: khubd timed out on ep0out dmesg> usb 1-4: khubd timed out on ep0out dmesg> usb 1-4: device not accepting address 16, error -110 etc. etc. (full log here: http://erina.nerim.net/zMate/dmesg-2.6.10-rc2.txt) If I rmmod ehci-hcd, the device works fine in USB1 mode on 2.6.9, but some weirdness occurs on 2.6.10-rc2 (it gets "noticed" by the ub driver, says it is on /dev/ub/a, but that device doesn't exist, but that's a different story which I haven't looked into). On Debian unstable's 2.4.27-1-386 kernel, it seems to work OK with the ehci module: dmesg> ehci_hcd 00:10.3: VIA Technologies, Inc. USB 2.0 dmesg> ehci_hcd 00:10.3: irq 11, pci mem d0aa8800 dmesg> usb.c: new USB bus registered, assigned bus number 1 dmesg> ehci_hcd 00:10.3: USB 2.0 enabled, EHCI 1.00, driver 2003-Dec-29/2.4 dmesg> hub.c: USB hub found dmesg> hub.c: 6 ports detected dmesg> hub.c: new USB device 00:10.3-3, assigned address 2 dmesg> WARNING: USB Mass Storage data integrity not assured dmesg> USB Mass Storage device found at 2 dmesg> Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0 dmesg> SCSI device sda: 31360 512-byte hdwr sectors (16 MB) dmesg> sda: test WP failed, assume Write Enabled dmesg> /dev/scsi/host1/bus0/target0/lun0: p1 dmesg> usbdevfs: USBDEVFS_CONTROL failed dev 1 rqt 128 rq 6 len 10 ret -32 A few items grabbed under 2.4.27 which may be of interest: - http://erina.nerim.net/zMate/dmesg-2.4.27-i386-1.txt - http://erina.nerim.net/zMate/lsusb-2.4.27-i386-1.txt - http://erina.nerim.net/zMate/proc.bus.usb.devices-2.4.27-i386-1.txt Any ideas on what I should try next please?
