* usrp1: Wait for USB device renumeration only when necessaryThomas Tsou2010-08-272-3/+4
| | | | | | Waiting for FX2 renumeration is only needed after a firmware load so move it out of the main device discovery loop and into the firmware load itself.
* usrp1: Handle degenerate managed send buffer casesThomas Tsou2010-08-271-4/+19
| | | | | | | | Handle degenerate usage of send buffer commits. If the buffer is destroyed without ever being submitted, submit a zero byte transfer to return control to the underlying structure. If a committed buffer is re-committed, then report an error message and return 0 bytes back.
* usrp1: Disable default debug output for libusb implementationsThomas Tsou2010-08-273-3/+3
|
* usrp1: Cleanup libusb device handlingThomas Tsou2010-08-273-33/+50
| | | | | | | | This patch limits all libusb device enumeration operations to FSF (Vendor ID = 0xfffe) devices, which removes a lot of unncessary libusb output when debug mode is enabled. The reference counts held by the libusb device list are also reduced, which prevents holding references to unused devices.
* usrp1: Disable i2c error messages unless debug is enabledThomas Tsou2010-08-271-2/+4
| | | | | | Failed i2c operations can be normal under certain situations. Notably, write failures are used to detect unpopulated daughterboard slots.

| | | | | | | | 500ms is not enough. 1-2 seconds is suitable.

| * | usrp1: Modifiy USB transport implementations to use new interfaceThomas Tsou2010-08-267-314/+322
| | | | | | | | | | | | Common libusb1 code is consolidated in the libusb base file.
| * | usrp1: Modifiy USB interfaces to use new device handleThomas Tsou2010-08-266-69/+86
| | | | | | | | | | | | | | | | | | | | | The interface previously defined a descriptor type, which is now replaced with a generalized handle. This change provides more flexibility in implementations that may pass internal representations of device handles or identifier objects.
| * | usrp1: Remove unused overrun/underrun poll variableThomas Tsou2010-08-241-2/+0
| | | | | | | | | | | | | | | | | | The polling inverval for overrun and underrun checking is rate dependent and calculated in the dsp code whenever the interpolation or decimation is changed.

| * | usrp1: Change codec transmit gain scalingThomas Tsou2010-08-191-2/+2
| | | | | | | | | | | | | | | | | | The AD9862 datasheet states that maximum gain is achieved with a value of 111111 (0x3f), however, empirical testing reveals that the gain scaling value spans the full register width of 8-bits.
| * | usrp1: Make underrun/overrun checking rate dependentThomas Tsou2010-08-191-10/+22
