USB-Serial communication not working on Linux (Bill Validator GBA ST2) -


i trying communicate gba st2 bill validator using usb-serial connection. works fine on windows (the device attached com port) not on linux (so far ubuntu 14.04, 16.04 , debian 8).

by default cdc_acm drivers used attached /dev/ttyacmx, not answer request. (however when requested while in sleep mode wakes instantly).

related output of dmesg , lsusb:

$ dmesg [26600.821389] usb 2-1: new full-speed usb device number 37 using ohci-pci [26601.307233] usb 2-1: new usb device found, idvendor=16f9, idproduct=0003 [26601.307237] usb 2-1: new usb device strings: mfr=1, product=2, serialnumber=3 [26601.307239] usb 2-1: product: gba st2 [26601.307240] usb 2-1: manufacturer: astrosystems [26601.307242] usb 2-1: serialnumber: 06010010001 [26601.316173] cdc_acm 2-1:1.0: ttyacm0: usb acm device  $ lsusb -t /:  bus 02.port 1: dev 1, class=root_hub, driver=ohci-pci/12p, 12m     |__ port 1: dev 37, if 0, class=communications, driver=cdc_acm, 12m     |__ port 1: dev 37, if 1, class=cdc data, driver=cdc_acm, 12m /:  bus 01.port 1: dev 1, class=root_hub, driver=ehci-pci/12p, 480m

when forcing device use usbserial driver, able use under linux vm (virtualbox hosted on windows), not on plain linux machine. used following commands use usbserial driver:

sudo modprobe -r cdc_acm sudo modprobe usbserial vendor=0x16f9 product=0x0003

related dmesg , lsusb output:

how can communicate device under linux? idea appreciated.

depends on protocol bill validator uses @ moment, according http://www.intelligentvending.co.uk/payment-systems-telemetry/banknote-readers-note-stackers/gba-st2.htm able communicate on cctalk, mdb, parallel, pulse, serial, ssp

you can communicate cdc acm device using socat. example using socat send @ commands on https://unix.stackexchange.com/questions/97242/how-to-send-at-commands-to-a-modem-in-linux

socat establishes connection command sequences have send depends on present protocol of bill validator...

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -
