Hi everyone,
We consider it's not the appropriate status of E220 which has no CD-ROM. In
MS-Windows, while plug the device into PC with the driver already installed,
the OS will send a SET_FEATURE command to it. Then our device receives the
signal and switchs from one CD-ROM to one CD-ROM + two serial ports. We wanted
to achieve that also in Linux but as we had no experience in Linux field we
didn't know how to get the job done.We found that program whi
ch Santos mentioned previously, according to the source of it ,we understood
that it's also uses the SET_FEATURE command.
We'll distribute a software and put it on "well known locations" later. But
before that, we need your help to make a rounded solution of E220 on Linux. Now
we are making Linux applications just like the ones for MS-Windows.The best
modality for that:
1.put the E220 Linux applications and user-manual on the CD-ROM
2.As soon as E220 connect to PC ,CD-ROM is reserved and two serial ports comes
out.
3.The same time as step 2 ,if the application not installed, it will be
installed automatically. If the application is already installed, it will start
running automatically, just like the situation in Windows.
step 1 and step 2 takes the highest priority. We can do step 1 all by ourself
and ask for help to achieve step 2.
Any advises will be greatly appreciated.
best regards to you all
Linlei
