| 07:33.52 | ilew | sicelo: Fair point. Sorry should've added that bit. |
| 07:37.55 | ilew | merlin1991: With help from pali, with the newest ke-recv when the phone is rebooted the usb state is PC-suite mode. I don't know if it forgets it's previous state or there's a new default. |
| 07:40.47 | ilew | This means that when you plug the phone into a PC and you don't select a mode. The phone says it's charging but bq27200.sh reports the phone as discharging. |
| 07:42.48 | ilew | To fix it you have to select 'Mass storage mode' and then replug it into the pc. Then it charges fine until the next boot. |
| 07:44.46 | ilew | I'm not sure if pali found anything further. |
| 10:36.44 | merlin1991 | thanks for the explanation, I'll give it a test on my device and then adapt the repo |
| 10:37.10 | merlin1991 | or rather will adapt the repo now |
| 10:40.14 | merlin1991 | done |
| 10:47.33 | sicelo | i can confirm that! only seen it once (i don't use USB to PC much, if at all) |
| 10:48.33 | sicelo | but a few days ago, i set up usb networking on my N900, and N900 never charged. i thought the problem was on the laptop, but i see now |
| 11:01.05 | sicelo | i'm happy to hear about the workaround in the meantime |
| 13:31.42 | DocScrutinizer05 | (charging) that's pretty odd, charging should be unrelated to any USB data mode |

| 13:40.39 | DocScrutinizer05 | I don't understand how it interferes at all |
| 13:41.11 | DocScrutinizer05 | flaw in concept |
| 13:41.31 | sicelo | i didn't think that was the problem at all - blamed my laptop's USB ports for not charging. |
| 13:41.36 | DocScrutinizer05 | the only USB mode interfering with charging is hostmode |
| 13:42.29 | sicelo | it's a bug/regression in that version of ke-recv ... for example stock device has no issue |
| 13:42.40 | DocScrutinizer05 | and for hostmode there are exactly two triggers: ID pin grounded, or via software/GUI andn user interaction |
| 13:44.18 | DocScrutinizer05 | sicelo: for the PC it's also irrelevant if the device is in mass stoare mode, or "PC suite" mode, or simply "just charging" |
| 13:45.21 | DocScrutinizer05 | if anything is relevant for PC then that's power negotiation during USB ENUM |
| 13:45.31 | DocScrutinizer05 | and most PCs simply don't care |
| 13:46.02 | sicelo | reason i blamed my ports - the usb cardbus card is temperamental ... sometimes i have to suspend the laptop first before usb device enumerates |
| 13:46.16 | DocScrutinizer05 | there are fast charger ports on USB hubs and some PCs, they have additional modes |
| 13:46.38 | sicelo | and all onboard ports are dead (Thinkpad X40 - known issue) |
| 13:46.46 | DocScrutinizer05 | ouch |
| 13:48.38 | DocScrutinizer05 | >>The phone says it's charging but bq27200.sh reports the phone as discharging.<< might mean USB ENUM negotiated only 100mA but the device needs >100mA for operation, so it drains battery (bq27k reports "discharging") despite technically the device is charging from a USB point of view |
| 13:49.26 | DocScrutinizer05 | stock maemo popped up a warning notifier in such situation, with "The USB power is not sufficient" or words to the effect |

| 15:29.04 | DocScrutinizer05 | >>The phone says it's charging but bq27200.sh reports the phone as discharging.<< needs some correction: bq27200.sh only checks *battery* status, not phone status. See above |
