1. If you are using Smargo cardreader on PC (Linux server), then use this config in oscam.server:

[reader]
label                         = xx
protocol                      = smartreader
Device             = Serial:Reader xx
caid                          = xx
ident                         = xx
smargopatch                 = 1 #you can leave this line
rsakey                        = xx
boxkey                        = xx
detect                        = cd
mhz                           = 357
cardmhz                       = 357
group                         = x
emmcache                      = 1,3,2

How to find out device info?

Type these lines in telnet:  lsusb -v | grep iSerial
You should get something like this (this is an example!):

iSerial 3 Reader 129

Now you can add this in oscam.server:

Device = Serial:Reader 129

Smargo cardreader will now work in OScam without any issues, even after rebooting your PC. Number 129 doesnt change. What you need is make sure your smartreader is updated to v. 1.4! I think that newer versions of firmware have problem with providing this useful information!

2. If you are Smargo cardreader in Dreambox, VU+ or Xtrend/CT, please use this config in oscam.server:

[reader]
label                         = xx
protocol             = smargo #you can also try mouse instead of smargo
device              = /dev/ttyUSB0 #if you have more smargos, just use /dev/ttyUSB1, /dev/ttyUSB2, etc.
caid                          = xx
ident                         = xx
smargopatch                 = 1
rsakey                        = xx
boxkey                        = xx
detect                        = cd
mhz                           = 357
cardmhz                       = 357
group                         = x
emmcache                      = 1,3,2
