[linux-usb-devel] Kingston USB 2.0 pen drive not working properly in 2.6.10

I've got a Kingston DataTraveller Elite 1GB USB pen drive that I'm using with an Asus A8N-SLI Deluxe motherboard (nForce4 chipset). I was able to get the USB 2.0 to basically work in 2.6.10 thanks to the patch that David Brownell kindly provided. However, I'm having the following problem:

This USB drive works in 2.6.9, although the kernel is not too happy about it at first:

hub 1-0:1.0: connect-debounce failed, port 9 disabled

etc.

In 2.6.10 however, I get only the errors below when I plug the drive in. At least most of the time.. I think I may have gotten it to come up once. (This output is with CONFIG_USB_DEBUG=y)

Now if I rmmod ehci-hcd and plug it in then, it works perfectly with OHCI:

ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus [6] = 0x00100103 PRSC PPS PES CCS usb 2-7: new full speed USB device using ohci_hcd and address 14 ohci_hcd 0000:00:02.0: GetStatus roothub.portstatus [6] = 0x00100103 PRSC PPS PES CCS usb 2-7: new device strings: Mfr=1, Product=2, SerialNumber=3 usb 2-7: default language 0x0409 usb 2-7: Product: DT Elite HS 2.0 usb 2-7: Manufacturer: Kingston usb 2-7: SerialNumber: 09A11B4150306B2E usb 2-7: hotplug usb 2-7: adding 2-7:1.0 (config #1, interface 0) usb 2-7:1.0: hotplug usb-storage 2-7:1.0: usb_probe_interface usb-storage 2-7:1.0: usb_probe_interface - got id scsi9 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 14 usb-storage: waiting for device to settle before scanning Vendor: Kingston Model: DT Elite HS 2.0 Rev: 5.02 Type: Direct-Access ANSI SCSI revision: 00

etc.

It looks almost like 2.6.10 with EHCI is not waiting long enough for the device to initialize after the connect and then gives up too quickly, while in 2.6.9 it was eventually able to initialize. This drive has an activity LED on it, which after I plug it in with 2.6.10 just sits there without blinking (power on but no activity).
