<p>Hi Vincent,</p>
<p>Thanks for the patch.</p>

<p>I have tried the patch on snv_b50 (as b51 is deadlocking on boot right after the installation reboot). It has overcome the deadlock and it seems to initialize the device (the blue led turns on). OHCI attaches to it and shows a new usb hub with 2 usb connections. On the first one, usb_mid attaches and provides lots of interface and endpoint nodes under /devices. However, I was expecting this device to attach to a usbser-like driver. How can I know which driver (if any) provides support for my device and how can I force it to attach instead of the generic usb_mid?</p>
<p>Another remark: <b>cfgadm -l</b> lists the pcic0:slot0 entry as connected and configured, and <b>cfgadm -c {configure,unconfigure} pcic0:slot0</b> seem to work ok, but <b>cfgadm -c disconnect pcic0:slot0</b> fails with a hardware-specific error. If I just pull the card out and reinsert it afterwards, it never attaches again (until reboot).</p>
<p></p>
