USB CF boot progress: can't load usbstor driver

[Mark K Vallevand]

I've followed the advice of Slobodan and others, and have made some progress
booting USB CF. I can boot through ntldr, boot.ini, and the drivers get
loaded, then BSOD B7. I've marked all usb drivers, usbohci usbhun usbstor,
as start at boot time (0). I've added the devices to the
CriticalDeviceDatabase in the registry. I'm not sure I've done that
correctly, because the usbstor driver does not load. After BSOD B7,
debugger shows this for "!devnode 0 1":

DevNode 0x84fb5a68 for PDO 0x84fea7b0
InstancePath is
"PCI\VEN_10B9&DEV_5237&SUBSYS_523710B9&REV_03\2&ebb567f&0&A0"

Previous State = DeviceNodeUninitialized (0x301)

The device not is initialized byt not started. By contrast, the debugger on
an IDE HDD boot with USB CF attached shows this for "!devnode 0 1":

I've tried and tried to get the device "USB\Vid_07d0&Pid_1102" or something
like it in the RequiredDeviceDatabase, but nothing works. The usbstor
driver never loads.

I'm beginning to think that USB RAM boot from SDI file is a better option.

Mark,

Have you changed Group value for following services: usbehci, usbuhci,
usbhub from "Base" to "Boot Bus Extender"?

Regards,
Slobodan

 

[Mark K Vallevand]

Yes, I did set it to "Boot Bus Extender" except that I just found out when
I checked that its supposed to be "System Bus Extender". I'm trying it
right now...

Nope. Still BSOD 7B.

Plan B. USB RAM SDI boot.

If your image is small less than 64 MB then RAM boot is more universal
solution (network, disk, flash, USB, whatever)
