Hi Lustosa, That sounds reasonable. I'm not all that familiar with the DSP, but it seems to me you'd rather have that working on the vision side as I don't know what it's network access capabilities are (or did you mean for the compression aspect?). The jpeg cameras seem to really over-compress the images to fit 30-60 fps into 12mbit/s; an uncompressed camera will be better for vision. I would stay away from the PT Grey cameras unless you want to spent a lot of unnecessary money... I have worked with their Bumblebee camera before and was not impressed with it, especially for the cost. Feel free to contact me directly if you want to talk more about cameras. If frame rate is not a big concern, then you are in good shape with the gumstix. I was able to pull 752x480 @ 16bits/pixel @ 52 fps over the OTG port without a hub, and without using more than 20% CPU @ 500 MHz.

Thanks for your response, Derek, I really appreciate that. when I connect the USB webcam to my Chestnut43 board, and I type in: df in my console, it shoes as following: root@overo:~# df Filesystem 1K-blocks Used Available Use% Mounted on rootfs 234528 228656 5872 98% / ubi0:rootfs 234528 228656 5872 98% / devtmpfs 248968 144 248824 1% /dev tmpfs 40 0 40 0% /mnt/.splash none 248968 144 248824 1% /dev tmpfs 248968 372 248596 1% /var/volatile tmpfs 248968 0 248968 0% /dev/shm tmpfs 248968 0 248968 0% /media/ram When I type in lsusb: root@overo:~# lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Btw, thanks for the previous instruction about creating a kernel include UVC camera driver, I followed that and flash it to my NAND but looks like it's still buggy since Gumstix doesn't recognize the webcam... Any idea about it? It's just my curiosity, would it be easier if I install ubuntu on my Gumstix?

Guys, I had a bad feeling about the USB HOST port on my Chestnut43 board, let me explain why: First, I tried to re-compile the kernel with UVC video camera driver followed by Derek's instruction in other post. (see http://gumstix.8.n6.nabble.com/How-can-I-get-quot-developer-image-quot-kernel-source-code-td4965579.html#a4965636) Second, I compiled modules: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- modules -j4 And then install those modules: sudo INSTALL_MOD_PATH=/media/rootfs make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- modules_install On Gumstix, I typed: root@overo:~# depmod (nothing seem to happen) Next, I connect the Logitech QuickCam Express (which was supported by qc-driver project) and I type: root@overo:~# lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub root@overo:~# No device detected... I tried to reboot, or plug in a USB Mouse, or Flash Drive but I still got nothing by typing 'lsusb' (Besides, the Flash drive has a light which will be on once plugged into PC USB port, but it never on the HOST port) So, I start thinking *maybe the Chestnut43 board has a faulty USB HOST port*? Googled that, and I found the following threads : http://gumstix.8.n6.nabble.com/Overo-Chestnut-USB-ports-td4370132.html http://gumstix.8.n6.nabble.com/USB-Host-problems-td662510.html http://neostix.com/hardware-design/product-changes-known-issues-a-eol/67-known-issues.html *Is there anyway I can justify whether I have a faulty USB port or not?* USB Webcam project is very important since its my school project, but looks like I have to solve the USB port issue first. Any idea about this situation? Thanks in advance.

What happens when you connect a powered USB hub that supports high-speed mode into the host port, then plug your QuickCam into the hub? If that doesn't work, what about plugging other USB devices into the hub, e.g. keyboard and mouse? Greg ________________________________ From: kfcandroid <kfc...@gm...> To: gum...@li...

Hi Greg, Thanks for your reply, I got a Belkin USB Hub, it does support high-speed mode, but it's powered by USB port. *Data Transfer Rate:* 480 Mbps *Data Link Protocol:* Hi-Speed USB So I guess that won't work with the HOST port. Next, I plugged in a USB Mouse (Belkin Optical Mouse, 5V, 100mA) and expect the red light lights up, but it failed. I also tried an old (Pentium 4 age) DELL USB keyboard, a Kingston Data Traveler 100 USB 2.0 Flash drive but none of them were detected by the 'lsusb' command This is really killing me since I don't have any tool to test it, so if anyone who has been through this issue or any idea will be greatly appreciated.

I know that does not make sense: You want your OTG to be in host mode, but you have to load a client mode driver. There was a refactoring of the OTG subsystem a while back (sometime in the 3.1 timeframe) that added this dependency. Try "modprobe g_ether" and see what happens. Other potential gadget modules are g_cdc, g_serial or g_mass_storage. Hopefully you have one of these modules already compiled. Once the module loads, the OTG subsystem probes the bus. It should then figure out you want to be in host mode and find your webcam. frank |

I would suggest a Belkin 4 port hub. (NOT THE 7 PORT VERSION) The 7 port version will not power "high power" devices like Alpha WiFi ... -----Original Message----- From: James Linder [mailto:ja...@ti...] Sent: Tuesday, October 30, 2012 7:48 PM To: gum...@li...

Hi James & William, Is that means once I plugged in a powered usb hub and my device should work w/out any problem? The one I'm using (Belkin as well) is like the one in following link: http://www.amazon.com/Belkin-F4U006-RED-Port-Travel-USB/dp/B001TK3R1O/ref=sr_1_4?ie=UTF8&qid=1351642934&sr=8-4&keywords=belkin+usb+hub+travel For the powered hub, I've found one on Amazon which looks like: http://www.amazon.com/Belkin-4-Port-Cable-Power-Supply/dp/B00004Z6KW/ref=sr_1_7?ie=UTF8&qid=1351642766&sr=8-7&keywords=powered+usb+hub you guys think it's a good idea to get this hub?

It worked!! After I connect the powered hub into the OTG port, the 'lsusb' could finally recognize my hub as well as logitech QuickCam.
