hi all
i make a pcb based on THS8135 EVM SCH,THS8135,TVP7002,TUSB3210 be used.now there is a problem. when i plug my board to pc with usb cable, the device manager find a new USB DEVICE with yellow question mark, but i can't install the driver successfully.i dont't know why.
hardware:the only different between my board and reference sch is that i connect PUR and DP with a resistor 1.5k.not a transistor.and pin21 connect to ground.(defined as ground in datasheet, defined as self/bus in doc sllu032a).
software:1,install apploder setup; 2, modify aploder.inf with Using the Apploder driver.3,copy new aploder.inf,aploder.sys & TUSB2136.BIN to same path named c:\apploder; 4, plug my board to computer , computer scan new hardware and find USB DEVICE; 5,i update the driver of usb device path to c:\apploder. 6,computer mention can't find file that nessary and update faild.(ps.usb detail:USB\VID_0451&PID_2136).
after then ,i try to connect my board by 'TUSB3x10 EEPROM Burner', but the soft can't find my board either.
besides,where can i get the firmware of THS8135 EVM,i mean the hex or bin file,not srouce code. is that for free?
ps. when i try above,i disconnect SCL signal between tusb3210 and eeprom.
