[sane-devel] HP ADF Support for chipset RT58822
Hello, 2010/8/20 Alejandro Imass aimass at p2ee.org Hi, I would like to know the current support for the several HP ADF scanners that share the common chipset. From what I could see, it seems that the hp3900 series driver should support most if not all HP scanners based on the RT58822 chipset. Nevertheless, I don't have enough scanner skills to actually confirm this. hp3900 focuses on RTS8822 and derivates. I don't know if RT58822 is just a mistake or another chipset. Here are the scanners we would need support for: 8290, 8350, 8390, 8420, 7800 I think our team has confirmed that all except for the 7800 share the same chipset. We can't confirm the 7800 because we haven't had access to it yet, but we will next week. All scanners I've tested using RTS882x don't provide ADF functionality so I didn't recognize any related register and hp3900 doesn't support it. Question: Is adding support for these as simple as adding their hardware ids to the lists in hp3900.xxx ? What else should we be aware of? hp3900 backend has extended options to test device's behavior using known settings from recognized chipsets but this chipset is a bit complex needing many data to be programmed (such as lamp settings, sensor type, sensor clocks, motor steps depending on supported resolutions and so on). The idea is analyze windows' driver to extract all necessary data that may be different in each scanner model. That may take some time.

[sane-devel] HP ADF Support for chipset RT58822
I have a couple of HP 8250 ADF scanners. Work nice, but when they get messed up, I have to plug them into a Win box. Then I can use them again. So some initialization and error detection SW is probably missing. Also, things like the duplex page feed doesn't work. I believe the avision driver is not getting any more development at this time. If you can tell me how to determine the architecture, without pulling them apart, I can do that.

[sane-devel] HP ADF Support for chipset RT58822
Avision-based machines use their own chipset, not related to RTS chipsets. allan On Fri, Aug 20, 2010 at 11:19 PM, Valentine Christian valentine.christian at gmail.com wrote: I have a couple of HP 8250 ADF scanners.?

I don't know if RT58822 is just a mistake or another chipset. With the hp3900 enabled scanimage -L says it's RT58822 but when I try scanimage -h -d hp3900 it doesn't have the usb hw code in the list so the driver croaks. I tried adding it by brute force to the code (just adding the hw code in every place I could find the other ones) but I couldn't get it to even get the scanner options. I didn't spend much time with it either; thought it was better to ask before I fry my client's scanners. ?All scanners I've tested using RTS882x don't provide ADF functionality so I didn't recognize any related register and hp3900 doesn't support it. Hmmm, so hp3900 doesn't support ADF. hp3900 backend has extended options to test device's behavior using known settings from recognized chipsets but this chipset is a bit complex needing many data to be programmed (such as lamp settings, sensor type, sensor clocks, motor steps depending on supported resolutions and so on). The idea is analyze windows' driver to extract all necessary data that may be different in each scanner model. That may take some time. Ok, well let me check to see if I can first determine the actual chipset, but I won't see the scanners again till tuesday.

Hi, thanks for your reply. Just to be sure, you are saying that the 8250 partially works with the avision driver?
