HTC Eris :: Can't Update Usb Driver During 1.5 - 2.1 Root Procedure

I am on a replacement phone. 1.5 updated to 2.1OTA trying to root per walkthrough instruction in guide forum.

Firmware 2.1
Baseband 2.40.00.01.22
Kernel 2.6.29-5898f66b
htc-kernel@and18-2 #1
Build 2.19.605.1 CL123435 test-keys
Software 2.19.605.1
Browser WebKit 3.1
PRI 2.11_002
PRL 51866
ERI 5

While following the instructions posted, Step II-10.
Have yellow exclamation in Device Manager,
Get this window during update driver step:
Cannot Continue the Hardware Update Wizard

The wizard could not find a better match for your hardware than the software you currently have installed.

I do have usb_driver folder:
c:AndroidSDKandroid-adk-windowsusb_driver
has subfolder amd64 and i386 along with
android_winusb
androidwinusb86
androidwinusba64
source.properties

AndroidSDK has Installed Packages: Usb Driver package, revision 3

I haven't been able to finish the steps and get ROOT to work.
adb shell commands give me "can't find device"

And keep up the awsome work. the original phone I loaded 2.1 leak v.3. Loved it! Replaced/ warranty exchanged due to poor call reception and echo-ing on the other end.
