Hi I have a problem wih my usrp1 when connecting to any pc, when I power on the system the led stays solid if I plug in a usb the led remains the same no change in state When I connect to my debian system I get the following error [ 275.640109] usb 1-1.4: new full speed USB device using ehci_hcd and address 5 [ 275.712118] usb 1-1.4: device descriptor read/64, error -32 [ 275.888115] usb 1-1.4: device descriptor read/64, error -32 [ 276.064117] usb 1-1.4: new full speed USB device using ehci_hcd and address 6 [ 276.136115] usb 1-1.4: device descriptor read/64, error -32 [ 276.312116] usb 1-1.4: device descriptor read/64, error -32 [ 276.488115] usb 1-1.4: new full speed USB device using ehci_hcd and address 7 [ 276.896038] usb 1-1.4: device not accepting address 7, error -32 [ 276.968117] usb 1-1.4: new full speed USB device using ehci_hcd and address 8 [ 277.376038] usb 1-1.4: device not accepting address 8, error -32 [ 277.376259] hub 1-1:1.0: unable to enumerate USB device on port 4 I was told by ettus support it maybe relating to my firmware corruption of eeprom, but I confirmed that my eeprom is NOT corrupted anyone is welcome to confirm . The other thing they mentioned which can allow me to connect or make usb work is RESET the flash anyone have any idea how to do this ? Just some tests we conducted D- = 3.2xx V D+ = drop power from 1.xxx down Any help appreciated |
