You are right, Dilwyn (as allways). I am sorry that i didn't follow this
discussion in that time.
We have probably need to implement a 2 layers drivers scheme. A general low
level driver managing communication protocol and a device driver over this
for each kind of periperal/device. I think a scheme like one implemented by
T Godefroy for ATAPI protocol (low level) and CD manager (high level - not
yet very high ....) can be a good general architecture.
It is true that available hardware becomes obsolescent in a very short
time, but I think that for some categories, things still more generic and
more stable. I am thinking about devices, such :
- Optical mouse (My real dream for QL)
- Storage device (external disks, CD/DVD and card reader/writer)
- Twain scanner
For others devices like webcams, printers, ... things may be harder to
follow.
My last thought will be that I am not saying that we "must" developp a new
performant hardware and there is or not a suffisient market..., but if we
do, we cannot dont consider implementing an USB port. I am affraid we
haven't the choice : there is no more serial mouse, IDE disks are on
falling side, centronics/serials printer are now souvenirs ....
Cheers.

This came up in discussion some time ago.
As you say, Alain, the need for drivers would be the deciding factor.
IIRC it's not the USB port driver as such, but the individual drivers
for any particular device connected to it as well.
Even on the PC scene, available harder becomes obsolescent in such a
short time that as soon as a driver got written I guess the hardware
would no longer be sold and quickly back to square 1.
(For those who don't know Alain, I think he wrote many QL programs in
QLCF software library many years ago!)

I am wondering from some time ago, if it is possible to consider an
USB
port implementation on a new QL hardware. This, it will be a real leap
for
the QL community as it opens the door for a planty of low cost and
efficient peripherals and gets down the need for developping others
extensions. I don't know if this kind of thing could be looked in this
project but if it is, i will be interested for a couple of pièces. I
must
however admit that the need for drivers for a such devices will be
determinant.

.. but not graphics I think. That would still have to be down to the
motherboard.
