1) do all USB items need a driver to be installed?
2) is a USB dialup modem likely to be very easy to install, or something
needing special attention (perhaps avoided) - like a PCI internal
dialup modem?
3) if a driver is in principle necessary - do *all* PCI and USB item
drivers need compiling into the kernel? Is this how drivers are used?
Details:
I am at a stage of looking at the basics of dial up modems (as newb),
although my main internet connection is adsl via lan and router.
A serial modem was ok and easy once I got the idea of the port (using
yast) and then changed the PC bios setup which had nominated a
particular (different) interrupt for that port.
(I have an internal PCI modem, Intel chip - not entirely software modem,
but also not entirely hardware modem either. It has a Suse driver which
I probably will be installing for the experience after having got some
helpful recent comments here).
I chanced across a very cut price USB modem this morning, and being
'external' I thought it worth the 5 ukpounds (7 usdollars?). The USB
cable is worth something anyway, and I have enough to do with
windowboxes that the modem will get used sometime, somehow, anyway.
I plugged the (modem) usb cable into a socket into an already running
Suse 9.1, no modem lights came on. It does not have an external on/off
control.
I restarted the PC. I can see that USB is scanned at start-up.
I used yast, hardware devices, modem, it was not recognised. I
configured a modem device with various details including USB port (later
tried them all - ttyACM0 throughttyACM3) and then used Kinternet to
dialup, but still no apparent activity.
I was glad to see a whole bunch of information in
yast,hardware,hardware-information, USB, V90-modem-with-USB-interface,
(then 16 items apparently about it; including its maker connexant's
name)
I concluded that it had been effectively 'probed', so that was a start.
In windows this modem did not show lights ('on') until after its driver
was installed, when it showed continuously 'pwr on'.
I don't know anything about USB, but I am guessing now that USB devices
need a driver in the system before even they are recognised, and
subsequently, they are hot connect - is this the case?
Guessing further, since internal modems need particular drivers, is this
USB one also going to need a driver? Is this true for
*all* USB equipment?
