You can’t do thorough testing without both kinds of external hub, and you probably need an add-on PCI host controller card to make sure you have the other kind of USB 1. Userland software to call that driver, such as testusb. For full function support you must make sure Linux host side applications can use your peripheral, using some kind of device driver s. You should be able to run it for weeks and never see an error.

Linux USB Test Mode

There are probably a dozen or more other vendors; look around. Here’s a summary ubtest a different test run, with more tests and firmware that doesn’t support the ISO transfer tests 15 and The other is the driver output, which is captured by the “syslog” daemon given an appropriate “syslog.

That forces it uwbtest use the lower speed, a possible but unlikely configuration. Most of these tests can be run in modes where they verify that data matches some specific pattern.


You won’t notice issues with class or vendor-specific functionality with the kind of test setup described here, or with some of the less-mainstream Linux-USB APIs. Issue various size writes. This one doesn’t answer to my question. You want to be sure to find and fix the kind of bugs these options uncover. Some peripherals can work through ‘usbfs’ with user mode device drivers; those peripherals tend to rely only on simple half-duplex protocols. Post as a guest Name.

Otherwise you should ask for your money back.

Exec format error Anyone Please post better simple explanation. Most Linux PCs should work just fine as the test driver. Use those to cover many different traffic patterns. Run “testusb -t2”, “testusb -t4”, “testusb -t6”, and “testusb -t8” to test bulk IN transfers. Sometimes hubs including root hubs behave differently during enumeration, which often reflects hardware problems.

Repeat the previous tests using gadgetfs and linus usermode test program, to test request queue depths greater than one. Full-speed or low speed tests connect peripherals in one of two ways.

Welcome to our website

The scatterlist tests can sustain peak transfer rates for some time, and all the test have modes where they can issue short writes. Sign up using Facebook. One test for control queuing covers some fault recovery modes. Linkx 11 and 12 aren’t very interesting from the perspective of the peripherals, but they cover some tricky code paths within HCDs and usbcore. That’s standard in current Linux 2.


You should ask for your money back. Those are chapter 9 tests control traffic that every USB device should be able to pass.

You should use that test script to make sure that enough of the interesting boundary cases are covered by your tests.

The usbtestt test is whether Linux-USB can enumerate your peripheral and parse its descriptors; that’s basic plugfest style testing. That’s clearly a good milestone, but it certainly shouldn’t be the last one! For example, both the SCSI and driver model code needed significant hot-unplug bugfixes.

Linux source code: drivers/usb/misc/usbtest.c (v) – Bootlin

Use ‘testusb -a’ to test all recognized devices in parallel one thread per device. In fact, testing the hardware-specific controller driver relies on gadget zero and host side tests like these. Closed-source drivers are undesirable, and can’t usually be bugfixed. Other than the old usbstress 0.
