Yep, I think I got that problem that'd been so annoying. With
current CVS and a prototype USB 2.0 storage device, this now
hotplugs usb-storage ... usb-storage gets past its first bulk request,
hangs on the second, and then gets unhappy when I unload the
ehci-hcd module while it's still trying to probe that device! :)
Now would likely be a good time for folk who have access to
USB 2.0 devices to start finding more bugs. Ones fixed since
the last snapshot (ehci-0305.patch) include:
- enumeration works without needing a usbcore hack;
- uses pci_pool
- fixes various nasties in the rmmod/disconnect paths;
- fixes for readl/writel ... pci write posting, no byteswapping
- should behave on some systems with 64bit dma_addr_t
- deletes microframe-level scheduling hook
- random other updates
Related: USB 2.0 host controllers are in stores. Fry's lists
them for $50 (and up :), and they work fine with usb-ohci
(at "full" and "low" speeds) even if the "high speed" EHCI
support is still in development.
