fixing usb problem on unrooted EVO - impossible?

[leonidm]

Sorry for doubleposting - I've posted this in rooting thread but nobody replies andd I'm getting desperate:
I'm a long time EVO user and yesterdayI got my second one - White EVO HW 004 I've got for my wife. I carefully rooted it using HBOOT 2.02 instructions and it seemed to go well, besides the fact that it failed to FLASH radio, but it looks like alot of others had the same issue. So after rooting, I've booted in to a ROM and was able to verify that I have fool root access. So my next step was to FLASH OMJ ROM v4.0. This is where the things started to go wrong. I did whipe of everything and then selected FLASH ROM< from SDCARD. I got e:can't mount SDCARD: After rebooting EVO it vibrates 5 times quickly and dies. I can still boot in to bootloader and go to recovery. but bootloader does not like any of the PC36IMG.zip files I'm feeding it - it shows that it sees it and the progress bar moving on initial load, then checking it, then back to bootloader menu - i no longer get prompt to FLASH it. Recovery still can't mount SDCARD. I've tried using SDCARD from a working EVO - same problem. Am I screwed? Help please!
I've fanally solve this problem with what i've found on another forum:
[ How-To ] Fix SD card not being detected & USB port not working
[ How-To ] Fix SD card not being detected & USB port not working - xda-developers

fastboot oem enableqxdm 0

while in bootloader/fastboot - this force-mounted sdcard, and now , recovery could see OMJ ROM and FLASHed successfully.

However my USB port no longer working neither for charging nor for adb, and I'm no longer rooted as I FLASHed stock ROM (yes, stupid me, i know - i was hoping FLASHING stock will fix USB and i'll be able to re-root later)). There are some instructions on the same thread on how to recover USB port, but they require root, and I need USB to root, so I'm kind of in a dead loop. Am I beyond help now? Has anyone been able to recover from that?
