Ya slax sucks. One you spoof the Hitachi to something like a benq or liteon or probably even samsung slax can no longer find it to put it in mode b.
When this happened to me i used the command prompt dos utility modeb.exe
modeb xxxx (where xxxx is the port you have your hitachi connected to)
But the reality of your problem is this. If its reading originals then you must have flashed it right. Unless you somehow flashed it with a original but it sounds like you know enough about what your doing that that is not it.
I bet either your laser is weak or your burns are weak or both.
I have been changing lasers steady in benq lately. Normally i only get hitachi's and samsungs into my shop but it seems benq laser fail just as often. If i were you i would try buying a laser and getting the benq working again.
You can try to do a pot tweak to improve your hitachi's performance while you wait for parts.
I am out of stock of benq lasers at the moment but i will have more by the end of next week.
