I am not familiar with your issue with the USB ports on an eMachine.
While perhaps that is the answer in your set of circumstances, in my experience that is not the issue in at least 99% of times users have difficulty loading an OS.

Don't use Desktop Manager to load an OS. It is phenomenal how often this is the issue for users. As the other member above posted, download the OS and install it on your PC, then load it to your devcice.
See my instructions in Post #2 of this thread:

The problem might be the browser you're using on your PC. For some reason some users experience some type of corruption when downloading anything directly from RIM (ie the official BB site) using Firefox or Chrome. I'm a diehard FF fan, but unfortunately I fall into this category. (I also have the issue with Adobe updates.) I had to uninstall DM and re-download it, and the same with OS's. I now keep my "default" browser as IE just because of DM and Adobe auto-updates.

Carrier's store or tech support staff won't be much help. It is rare that a user's issue is actually hardware-based. Unless the issue was ultra-basic, the store won't be any help. And tech support will offer little support too. There are dozens, if not hundreds, of members here that each possess greater BB troubleshooting than you will ever find from your carrier's tech support. The knowledge base here is unparalleled.
So your points are intriguing and do offer one more possibility for a user's OS-install problems. Always great to know of further possibilities, so thanks for that.
I just worried that people might come across this first and think this was the answer to their woes when in most cases it will be irrelevant.
