Hi all,
I have tried some configurations with linux distributions (ubuntu and centos) with oscam.
Oscam was configured with a very cheap pcsc smartcard reader and I had optimal results (about 100ms of ECM).
My old pcsc smartcard reader is dead and the reseller suggest me to improve performance using a dedicate device like the smartreader+.
This is the beginning of a lot of problems !
The utilities that are used in smartreader+ are unusable in triple reader and I can't configure correctly the device.
With smartreader protocol, the device is not recognized.
With serial protocol, ATR is truncated, so the card isn't recognized correctly.
With smargo protocol, it works but ECM are unacceptable (about 265ms).
How can improve ECM time of about 100-120ms obtained with a very cheap pcsc smartcard reader?

This is my oscam.server configuration:

[reader]
label = smargo-0
protocol = smargo
device = /dev/ttyUSB0
device_out_endpoint = 0x81
smargopatch = 1
boxid = xxxxxx
detect = cd
mhz = 600
cardmhz = 357

thanks in advance
