Between the two threads, I made several suggestions and provided links to several sets of potential fixes. Some you said you did, other suggestions I made you didn't bother to respond to, apparently just assuming we are to know what you have done, and what the results were. Sorry, but we cannot make such assumptions.
For example, I provided a link that, had you followed, would have taken you to instructions on how to use Acer's eRecovery Management Program - a process that worked for other users with your restore problem. Was there a reply saying you even tried that? No.
I also provided a link showing others with your same problem where Acer tech support created new recovery media for them. Did you check with Acer? I don't know. Did you reply to tell me? No.
Then, after you complained your problem was not being fixed I apologetically explained it was not an unwillingness on my part, just that I ran out of ideas and provided yet another link showing you how to get a new recovery disk. But did you contact Acer? Again, who knows? You didn't reply to that either.
Instead, you commented about the lack of attention and concern I have given. I am sorry, but I guess we have a different definition of what being a professional means. If someone states he is does not know the answers and therefore is unable to help me, I sure don't accuse them of ignoring me or being unwilling or unconcerned!
I am sorry you feel the way you do. I fully understand the frustration when computer problems are not immediately fixed. But note I would never have attempted to help you in the first place if not concerned or willing to donate my spare time to help you. Please note the forums are flooded with people having countless USB problems and have been for years. If there was a simple fix to all these problems, the "USB Implementers Forum" (the consortium of industry leaders who create and set the standards for USB) would have fixed it long ago.
Once again, you have a used computer with multiple problems, no recovery disks, and no recovery partitions. My sincere advice is for you to contact Acer tech support and arrange for new recovery media and hopefully, that will fix your USB problems too. Otherwise, I hope zcomputerwiz has some more ideas to get your USB problems fixed. But if not, I hope you respect that he too tried the best he could. Good luck.
