Hi Joel, > That error looks interesting. The reason we deleted the old saleae-logic driver was so that we could get a wider audience of testers for this new driver, so this is helpful information.

I'm happy to test patches and supply extra info. > You do have the git head fx2lafw installed, right? Does this problem occur on all machines? Do you have more than one type of host controller in your machine? Do these make a difference? Yes, it's all the latest and greatest from git. It may be good to know that during testing the device was behind an usb hub. (it is working fine with the latest saleae software using this hub). I just removed the hub and connected the device directly to the pc. And now I am getting other errors: [1] sr: initializing fx2lafw driver sr: ezusb: uploading firmware to device on 1.23 sr: ezusb: setting CPU reset mode on... sr: ezusb: Uploading firmware at /usr/local/share/libsigrok/firmware/fx2lafw-saleae-logic.fw sr: ezusb: Uploaded 4096 bytes sr: ezusb: Uploaded 4096 bytes sr: ezusb: Uploaded 4096 bytes sr: ezusb: Uploaded 4024 bytes sr: ezusb: Firmware upload done sr: ezusb: setting CPU reset mode off... sr: dev: sr_dev_has_hwcap: requesting hwcap 2 sr: dev: sr_dev_has_hwcap: found hwcap 2 sr: dev: sr_dev_has_hwcap: requesting hwcap 2 sr: dev: sr_dev_has_hwcap: hwcap 2 not found sr: dev: sr_dev_has_hwcap: requesting hwcap 2 sr: dev: sr_dev_has_hwcap: found hwcap 2 sr: dev: sr_dev_has_hwcap: requesting hwcap 2 sr: dev: sr_dev_has_hwcap: hwcap 2 not found libusb:error [op_open] open failed, code -1 errno 19 sr: fx2lafw: Failed to open device: -1. sr: fx2lafw: Unable to open device. sr: session: sr_session_dev_add: dev_open failed (-1) Failed to use device.

But hopefully we can track down the problem in the next few days. Hope so too.
