Well, I've tried and in fact without old_scheme_first set ehci hands over the device to uhci, that fails to detect it. And in fact uhci is loaded at boot before ehci. I've modified this, but the behaviour is not ok: it seems that the device is detected ok even if already present at boot, but then I've a keyoboard/mouse lockup Dec 1 01:40:26 kefk kernel: ehci_hcd 0000:00:1d.7: port 3 high speed Dec 1 01:40:26 kefk kernel: ehci_hcd 0000:00:1d.7: GetStatus port 3 status 001005 POWER sig=se0 PE CONNECT Dec 1 01:40:26 kefk kernel: usb 1-3: new high speed USB device using ehci_hcd and address 3 Dec 1 01:40:26 kefk kernel: usb 1-3: new device strings: Mfr=1, Product=2, SerialNumber=3 Dec 1 01:40:26 kefk kernel: usb 1-3: default language 0x0409 Dec 1 01:40:26 kefk kernel: usb 1-3: Product: Mass storage Dec 1 01:40:26 kefk kernel: usb 1-3: Manufacturer: USB Dec 1 01:40:26 kefk kernel: usb 1-3: SerialNumber: 142E19413C2FCA34 Dec 1 01:40:26 kefk kernel: usb 1-3: hotplug Dec 1 01:40:26 kefk kernel: PCI: Setting latency timer of device 0000:00:1d.2 to 64 Dec 1 01:40:26 kefk kernel: uhci_hcd 0000:00:1d.2: irq 169, io base 0xb400 Dec 1 01:40:26 kefk kernel: usb 1-3: adding 1-3:1.0 (config #1, interface 0) Dec 1 01:40:26 kefk kernel: usb 1-3:1.0: hotplug when cupds starts, that uses usb printer, the keyboard and mouse gets locked, simply no key press or mouse move are detected. (or, at least, it seems that cups driver loading causes the lockup, but I can try to repeat this). the first log row after cups loading is this: Dec 1 01:40:30 kefk kernel: ACPI: PCI interrupt 0000:03:04.0[A] -> GSI 20 (level, low) -> IRQ 209 But I don't think taht this can be so useful. Please let me know is different details are needed. This happens only when ehci is loaded before uhci and flash key is present at boot. If I keep unplugged the flash key the boot sequence goes on without problem, then I can plug and use flash key. I'm unable to see on the logs where something goes wrong, but if you can tell me if more data are needed I can cut&paste the logs. -- Fabio Coatti http://members.ferrara.linux.it/cova Ferrara Linux Users Group http://ferrara.linux.it GnuPG fp:9765 A5B6 6843 17BC A646 BE8C FA56 373A 5374 C703 Old SysOps never die... they simply forget their password. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
