I've been testing the heck, and this is what we have right now (on |
| 6 |
2.6.11-gentoo-r8, without any weird patch rather than Gentoo's ones |
| 7 |
which have nothing t do with USB and the like, nor modify the ABI as |
| 8 |
hardened-sources patch-set does): |
| 9 |
|
| 10 |
We have the following input modules: psmouse, sermouse, usbhid: usbkbd, |
| 11 |
usbmouse. |
| 12 |
|
| 13 |
Also, all USB-related code is modularized, as you can see in the |
| 14 |
attached .config . |
| 15 |
|
| 16 |
The case: |
| 17 |
|
| 18 |
we unload psmouse, hence ALPS touchpad (this is HP zv5045eu laptop, the |
| 19 |
amazing world of almost-unsupported stuff ;) stops working. |
| 20 |
immediately we load the usbmouse module which shouldn't be needed due to |
| 21 |
usbhid, and we don't get the mouse working but at least, it shows up |
| 22 |
without the "bad cable" error: |
| 23 |
|
| 24 |
drivers/usb/input/usbmouse.c: v1.6:USB HID Boot Protocol mouse driver |
| 25 |
|
| 26 |
then we load psmouse again..., and we get: |
| 27 |
|
| 28 |
drivers/usb/input/usbmouse.c: v1.6:USB HID Boot Protocol mouse driver |
| 29 |
hub 4-0:1.0: Cannot enable port 1. Maybe the USB cable is bad? |
| 30 |
|
| 31 |
At this point, it's evident that psmouse and sermouse aren't able to |
| 32 |
co-exist with usbhid or usbmouse (BTW, my host controllers are EHCI and |
| 33 |
OHCI, no UHCI thingy). |
| 34 |
|
| 35 |
The complete process: |
| 36 |
|
| 37 |
usbcore: deregistering driver usbmouse |
| 38 |
usbcore: deregistering driver usbhid |
| 39 |
usbcore: deregistering driver hiddev |
| 40 |
usbcore: registered new driver hiddev |
| 41 |
usbcore: registered new driver usbhid |
| 42 |
drivers/usb/input/hid-core.c: v2.0:USB HID core driver |
| 43 |
usbcore: registered new driver usbmouse |
| 44 |
drivers/usb/input/usbmouse.c: v1.6:USB HID Boot Protocol mouse driver |
| 45 |
ALPS Touchpad (Glidepoint) detected |
| 46 |
Enabling hardware tapping |
| 47 |
input: AlpsPS/2 ALPS TouchPad on isa0060/serio4 |
| 48 |
hub 4-0:1.0: Cannot enable port 1. Maybe the USB cable is bad? |
| 49 |
|
| 50 |
So, it's not a fault regarding my configuration or my hardware but a |
| 51 |
problem regarding the way that input drivers get registered and more |
| 52 |
important, how USB input devices register (well, I think psmouse should |
| 53 |
get built-in, but I'm lost, I've lost the count on the times I have |
| 54 |
plugged, unplugged, recompiled and compiled again, and this host won't |
| 55 |
be able to suffer more plugging-unplugging insane fun). |
| 56 |
|
| 57 |
I've been looking fr other people with the same issue and there are a |
| 58 |
few, they're lucky that they have PS2 but this laptop has "obsoleted" |
| 59 |
those nice ports. |
| 60 |
|
| 61 |
The device works on a USB 1.1 host controller-powered machine running |
| 62 |
hotplug, udev and more concretely Ubuntu Linux Hoary (from the last I |
| 63 |
time I used it, that was before my CRT screen got out of business...), |
| 64 |
so, It may concern USB 2.0 EHCI controller and the way it does or |
| 65 |
doesn't the supportability for low-velocity USB 1.1 (but it works with |
| 66 |
an HCI device which is based on the BlueFritz! chip, that is, bfusb |
| 67 |
driver, and that's not USB 2.0). |
| 68 |
|
| 69 |
I hope to get this fixed for all of the users who suffer the problem of |
| 70 |
having 2.0 host controllers not working with USB mouses (among those |
| 71 |
like me who rely on a weird ALPS touch-pad, with the risk of getting |
| 72 |
those damn RSI). |
| 73 |
|
| 74 |
Cheers and many thanks in advance. |
| 75 |
PS: No, it's not "Tom's hardware" week here, even if it looks like that |
| 76 |
to me. Just bad luck ;). |
