Reading Weighing scale data from USB host in Yun

-

hello,


i have weighing scale machine support usb interface report weight of item. have connected usb interface arduno yun's usb host. found connected/listed under /dev/bus/usb/001/00x. know how read incoming weight interface.

i tried below stuff without success:
 
1. when connect usb inteface on windows box, com port , able read weight there.

2. don't see device under /dev/input/eventx.

3. tried running python script opens '/dev/bus/usb/001/00x' , dumps data no success.

4. 'lsusb' command list device '/dev/bus/usb/001/00x' believe there enough drives installed.

do have correct usb/serial driver installed? if so, should see /dev/ttyusbx device.

kind regards,

jos

so having newest version of rasbian there isnt guids. in command propmt instructed sudo nano /etc/dhcp.conf first off should file empty lol?? because there's nothing in mine. im using eth0 & need commands/ enter /etc/dhcp cd .conf append along lines of code: select all interface eth0 static ip_address=192.168.0.10/24 static routers=192.168.0.1 static domain_name_servers=192.168.0.1 8.8.8.8 raspberrypi

arduino bug sur secteur, batterie, mais pas en usb?

bonjour, je travaille sur un premier projet de barrière infrarouge pour photographier les oiseaux, https://www.youtube.com/watch?v=8xzqd9iefgy&feature=youtu.be quand je suis alimenter en usb tout va bien, mais lorsque je passe par une alimentation extérieur (9v 12v secteur 12v) plus rien ne marche, la led clignote, les relais basculent n'importe comment. il me semble que se sont les capteurs qui bugs...(pas assez de courant?) 2 capteur ir = 2x100ma 2 relais = 2x40ma 1 diode, 1 push buttom la carte elle même... on est environ à 400ma. je ne comprends pas pourquoi ça coince!   le régulateur de la carte est prévu pour alimenter la carte et quelques petits accessoires pas trop gourments en courant. si on lui en demande trop il chauffe et la tension délivrée s'effondre. l'usb est, elle, prévue pour délivrer jusqu'à 500 ma. avec tous les ma consommés il faut une alim 5v supplémentaire. alim 5v +/- 5%, avec le 0v relié à celui de la carte...
