[Bug 154787] Re: ZyDAS USB zd1211rw wireless key usually not recognised by kernel
Using uhci_hcd rather than ehci_hcd does indeed work, but it's not an ideal solution.

*** This bug is a duplicate of bug 88746 *** https://bugs.launchpad.net/bugs/88746 HI Dennis, I agree this is not a proper solution but a workaround to get thing running for you. My main concern was distinguishing if this report is indeed a duplicate of bug 88746. As such it should be marked appropriately. I'll go ahead and mark this as a duplicate of that report.

There's a few workarounds listed there, and certainly some updates since I haven't booted that system for quite a while now (running a MacBook now... :)). I'll try them later and see how it goes.

This seems to be a duplicate of bug 88746. Care to try the workaround mentioned there? (ie don't reload the ehci_hcd module). Let us know if this helps.

[Bug 154787] Re: ZyDAS USB zd1211rw wireless key usually not recognised by kernel
I am having the same problem. Likewise, it started with the final pre- Gutsy Feisty kernel, and is still present in Gutsy. My wireless network card was immediately recognized by a friend's Gutsy installation, so there is clearly scope to fix this problem with the existing kernel. I've considered using the zd1211rw-mac80211 module, but it is not found by modprobe on my system and I could find no user-level instructions on how to make it available.

[Bug 154787] Re: ZyDAS USB zd1211rw wireless key usually not recognised by kernel
That's interesting, I didn't know they were replacing the 802.11 stack... but I don't see why they'd rewrite any of the parts of code that deal with the USB end of things really - that being the point of modularity. That said, I don't know much at all about USB and how it's handled in-kernel... I see from lsmod that the usbcore module is used by (among many others) zd1211rw, and although ehci_hcd is used by nothing, it clearly performs some vital functionality since removing it stops my USB keyboard from working. I get the feeling that the problems I mentioned are related to usbcore and/or ehci_hcd, from the syslog messages. For example, the problem reappears after suspend and resume, with the following messages (I have to remove and reinsert the wireless stick): [ 10.117198] hub 4-1:1.0: Cannot enable port 3.
